Abstract:

Good interprofessional work (IPW) is essential to provide quality home-based end-of-life (EOL) care. The purpose of this study was to explore the factors of “good collaboration,” as evaluated separately by home care nurses (HNs), home helpers (HHs), and care managers (CMs). The relationship was examined between their evaluation of good collaboration and their recent actual experience of interprofessional collaborative work for a home-based EOL case. The questionnaire was returned nationwide by 378 HNs, 305 HHs, and 476 CMs, and data were collected on 177 EOL cases from HNs, 84 cases from HHs, and 123 cases from CMs. Evaluation of good collaboration by HNs was associated with working with a CM with whom they had multiple collaborative experiences, the client being independent for their toileting until just before dying, and sharing information regarding the client’s EOL decision with an HH 1 month before dying. Evaluation of good collaboration by HHs was associated with working at an agency that collaborated with fewer CM agencies and working at an agency that allowed staff to visit dying clients. Evaluation of good collaboration by CMs was associated only with the client being dependent for toileting. Our results highlighted the characteristics of how each professional seeks to collaborate depending on their preparedness, contexts, and resultant expectations toward other professionals when entering the IPW for home-based EOL care. To promote good IPW for home-based EOL care further, professionals need to understand these differences among ourselves and try to meet others’ expectations.

Abstract:

Purpose – This study aims at developing a better understanding of the different mechanisms that affect technology collaboration portfolio management. How do firms manage their technology collaboration portfolio? Despite some thoughtful scholars have advanced the understanding of the phenomenon of technology collaboration portfolio, there is not much research that has been done in terms of understanding the endeavors of firms when they collectively use a range of actors for the best interests of the firms. Additionally, little attention has been paid to the trade-offs and managing mechanisms for the collaborations between different partners from a portfolio-level perspective, especially in emerging markets. Design/methodology/approach – A multiple-case study of two Chinese high-tech firms, an inductive approach. Findings – The authors identified three primary mechanisms that underlie successful knowledge creation and application in technology collaboration portfolio context: informally mobilizing boundary-spanning brokers for domestic academic collaborations, formally institutionalizing learning activities for industry collaborations and integrating formal and informal mechanisms for technology collaborations between focused firms and foreign organizations. Originality/value – The authors extend the line of organizational ambidexterity literature with a focus on strategic alliance, proposing that firms need to balance academic and industry collaborations from a portfolio level. Moreover, the authors intend to extend the literature of alliance portfolio by suggesting three different learning mechanisms of managing different technology collaborations for the purpose of balancing successful knowledge creation and application.

Abstract:

Purpose The purpose of this study is to identify the factors determining collaborative innovation effect of manufacturing firms in emerging economies. Design/methodology/approach Based on a survey of 1,206 Chinese manufacturing firms and using structural equation modelling, this study explores the factors determining the effect of collaborative innovation among manufacturing firms (namely, internal capabilities, government policies, collaboration mechanisms and social networks) and examines the relationship between collaborative innovation effect and innovation performance. Findings The study finds that there are significantly positive relationships between firms’ internal capabilities, government policies, collaboration mechanisms and social networks and collaborative innovation effect among firms. Practical implications These findings reveal that policymakers should create an effective institutional culture and market environment to facilitate firms’ collaborative innovation. Originality/value This paper draws on the resource-based view of firms and contributes to understanding of how the development of factors determining firms’ collaborative innovation effect can improve innovation performance. This study extends established frameworks on collaborative innovation in relation to four dimensions, namely, firms’ internal capabilities, government policies, collaboration mechanisms and social networks, uniquely identifying the limits of specific dimensions. Moreover, this study addresses government policies and “Guanxi culture” specific to China that provide new insights into how firms’ collaborative innovation is improved from the perspectives of business–governmental relations and social networks.

Abstract:

Teams of scientific specialists have replaced independent researchers, simultaneously the research team size has increased by 50% over the 19‑year period. Better collaborations between project team members might improve research outcomes or R&D project products. Knowledge needs to be communicated among a research team effectively and shared among all research team members as it is created collaboratively. Collaboration can be successfully supported by providing a knowledge sharing environment and communication facilities. The purpose of this paper is to evaluate the feasibility and discuss novel communication among scientists using a content management system (CMS) which operates based on the Software‑as‑a‑Service (SaaS) cloud‑computing model. This study presents the use of CMS for the collaboration of a research team carrying out a research project funded by the Polish National Science Centre.

Abstract:

Within Australia, vitamins, minerals, nutritional supplements, essential oils, and homoeopathic and herbal preparations are collectively termed and regulated as Complementary Medicines (CMs) by the Australian Therapeutic Goods Administration (TGA). CMs are predominantly self-selected through a pharmacy, providing pharmacy personnel an opportunity to engage with the public about their CM use. CMs are currently non-scheduled products in Australia. This review aimed to summarize the literature reporting the potential effect on pharmacies if scheduling of CMs was adopted, using codeine as an example. A scoping review methodology was employed. Seven databases were searched to identify four key concepts, including: CMs, scheduling and rescheduling, codeine, and pharmacists. Seven studies were included for analysis. The majority of the literature has explored qualitative studies on the perception and opinion of pharmacists in relation to the up-scheduling of codeine. The case of codeine illustrates the possible impact of up-scheduling. If CMs were to be up-scheduled, the accessibility of CMs would be limited to the pharmacy providing a role for pharmacy personnel, including both pharmacists and pharmacy technicians, to counsel on CM use. However, careful collaboration and consideration on how such a regulatory change would impact other key-stakeholders, including CM practitioners, requires both a strategic and collaborative approach.

Abstract:

High Energy Physics (HEP) experiments will enter a new era with the start of the HL-LHC program, with computing needs surpassing by large factors the current capacities. Anticipating such scenario, funding agencies from participating countries are encouraging the experimental collaborations to consider the rapidly developing High Performance Computing (HPC) international infrastructures to satisfy at least a fraction of the foreseen HEP processing demands. These HPC systems are highly non-standard facilities, custom-built for use cases largely different from HEP demands, namely the processing of particle collisions (real or simulated) which can be analyzed individually without correlation. The access and utilization of these systems by HEP experiments will not be trivial, given the diversity of configuration and requirements for access among HPC centers, increasing the level of complexity from the HEP experiment integration and operations perspectives. Additionally, while HEP data is residing on a distributed highly-interconnected storage infrastructure, HPC systems are in general not meant for accessing large data volumes residing outside the facility. Finally, the allocation policies to these resources are generally different from the current usage of pledged resources deployed at supporting Grid sites. This report covers the CMS strategy developed to make effective use of HPC resources, involving a closer collaboration between CMS and HPC centers in order to further understand and subsequently overcome the present obstacles. Progress in the necessary technical and operational adaptations being made in CMS computing is described.

Abstract:

The most recent results of a Higgs boson production and properties from the CMS Collaboration using the LHC Run 1 and Run 2 data are reported. These include analyses of a Higgs boson decaying to a pair of photons, four leptons via Z boson pair decays and the associated production of a Higgs boson with top quark pair, predicted by the Standard Model (SM). The studies of a Higgs boson decays to a pair of bottom quarks, a pair of tau leptons and a charm quark pair are also presented. The Higgs boson production via vector boson fusion (VBF) and decaying to invisible particles is reported here as well. The analysis of a Higgs boson decay to a pair of muons is also presented. The study of a Higgs boson pair production at 13 TeV is performed as well and projections of a Higgs boson self couplings together with the couplings to other particles at the HL-LHC are made.

Abstract:

The CMS Collaboration has recently commissioned a new compact data format, named NANOAOD, reducing the per-event storage space requirement to about 1-2 kB. This represents a factor 20 reduction in storage space compared to the MINIAOD data format used previously for physics analysis at CMS. We envisage that the information stored in the NANOAOD data format is sufficient to support the majority of CMS physics analyses. NANOAOD also facilitates the dissemination of analysis methods and the automation of standard workflows for deriving conditions and object calibrations. The latest developments of this project will be presented.

Abstract:

Hundreds of physicists analyze data collected by the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider using the CMS Remote Analysis Builder and the CMS global pool to exploit the resources of the Worldwide LHC Computing Grid. Efficient use of such an extensive and expensive resource is crucial. At the same time, the CMS collaboration is committed to minimizing time to insight for every scientist, by pushing for fewer possible access restrictions to the full data sample and supports the free choice of applications to run on the computing resources. Supporting such variety of workflows while preserving efficient resource usage poses special challenges. In this paper we report on three complementary approaches adopted in CMS to improve the scheduling efficiency of user analysis jobs: automatic job splitting, automated run time estimates and automated site selection for jobs.

Abstract:

From the recently established lower-limits on the nonobservability of the neutrinoless double-beta decay of [Formula: see text]Ge (GERDA collaboration) and [Formula: see text]Xe (EXO-200 and KamLAND-Zen collaborations), combined with the ATLAS and CMS data, we extract limits for the left–right (LR) mixing angle, [Formula: see text], of the [Formula: see text] electroweak Hamiltonian. For the theoretical analysis, which is a model dependent, we have adopted a minimal extension of the Standard Model (SM) of Electroweak Interactions belonging to the [Formula: see text] representation. The nuclear-structure input of the analysis consists of a set of matrix elements and phase-space factors, and the experimental lower-limits for the half-lives. The other input are the ATLAS and CMS cross-section measurements of the [Formula: see text]-collisions into two-jets and two-leptons, performed at the large hadron collider (LHC). Our analysis yields the limit [Formula: see text] for [Formula: see text], by combining the model-dependent limits extracted from the double-beta-decay measurements and those extracted from the results of the CMS and ATLAS measurements.

Abstract:

DD4hep is an open-source software toolkit that provides comprehensive and complete generic detector descriptions for high energy physics (HEP) detectors. The Compact Muon Solenoid collaboration (CMS) has recently evaluated and adopted DD4hep to replace its custom detector description software. CMS has demanding software requirements as a very large, longrunning experiment that must support legacy geometries and study many possible upgraded detector designs of a constantly evolving detector that will be taking data for many years to come. CMS has chosen DD4hep since it is a high-quality, community-supported solution that will benefit from continuing modernization and maintenance. This presentation will discuss the issues of DD4hep adoption, the advantages and disadvantages of the various design choices, performance results, and the integration of the plugin systems from CMS and Gaudi, another open-source software framework. Recommendations about DD4hep based upon the CMS use cases will also be presented.

Abstract:

Abstract After the Phase-2 high-luminosity upgrade to the Large Hadron Collider (LHC), the collision rate and therefore the background rate will significantly increase, particularly in the high η region. To improve both the tracking and triggering of muons, the Compact Muon Solenoid (CMS) Collaboration plans to install triple-layer Gas Electron Multiplier (GEM) detectors in the CMS muon endcaps. Demonstrator GEM detectors were installed in CMS during 2017 to gain operational experience and perform a preliminary investigation of detector performance. We present the results of triple-GEM detector performance studies performed in situ during normal CMS and LHC operations in 2018. The distribution of cluster size and the efficiency to reconstruct high pT muons in proton-proton collisions are presented as well as the measurement of the environmental background rate to produce hits in the GEM detector.

Abstract:

The CMS experiment collected around 150 fb−1 of proton-proton collision data at s = 13 TeV during the Run-2 data taking period of LHC. The CMS RPC system provided redundant information for robust muon triggering, reconstruction and identification. To ensure stable data taking, the CMS RPC collaboration has performed detector operation, calibration and performance studies. After the end of Run-2, it was started the second LHC long shutdown period (LS2), an important opportunity for maintenance and preparation for the next data taking period (Run-3) and the installation of services in preparation for the Phase-II upgrade. The activities included maintenance of power, gas and online systems. In this presentation, the overall performance of the CMS RPC system during the Run-2 period is summarized as well as all the activities done in preparation for future data taking periods.

Abstract:

Weak management of interpersonal conflicts can lead to dysfunctional relationships with relevant consequences for couple and family well-being. Our purpose was to devise a single dimension scale to assess conflict management in romantic relationships. We focused on five relevant conflict aspects: competition, collaboration, avoidance, accommodating attitude, and compromise. Study 1 ( N = 405) confirmed the existence of a single latent dimension, which was defined as the Conflict Management Scale (CMS), and consists of 8 items unbiased by gender. In Study 2 ( N = 205), the CMS convergent validity with attachment, empathic self-efficacy, satisfaction, and decision-making in the couple was analyzed. In Study 3 ( N = 120), the CMS was administered to 60 heterosexual couples in order to further examine the validity of the newly developed single dimension scale. Results showed that the CMS might be considered a valid and handy tool for planning couple and family therapies.

Full text

Abstract:

To describe the transverse momentum [Formula: see text] distribution of charged hadrons at 1.96 TeV observed by the CDF collaboration, we propose a formula with two components, namely, hadron gas distributions and inverse power laws inspired by QCD calculus. The new formula based on a formula by Hagedorn in 1983 includes an integration of pseudo-rapidity [Formula: see text]. The data collected at 0.9, 2.76, 7 and 13 TeV by the ALICE, CMS, and ATLAS collaborations are also analyzed using various models including single component models as well as two-component models. The results by the use of the modified version of Hagedorn’s formula are compared with those by the use of the two-component model proposed by Bylinkin, Rostovtsev and Ryskin (BRR). We investigate whether or not there is an interrelation among our modified formula, a formula proposed by ATLAS collaboration, and the BRR formula. Moreover, formulas for the [Formula: see text] distributions in the nonextensive approach are discussed.

Abstract:

The CERN analysis preservation portal (CAP) comprises a set of tools and services aiming to assist researchers in describing and preserving all the components of a physics analysis such as data, software and computing environment. Together with the associated documentation, all these assets are kept in one place so that the analysis can be fully or partially reused even several years after the publication of the original scientific results. An experimentspecific submission and retrieval interface has been developed for the CMS Collaboration. It integrates with the CMS internal analysis registry (CADI) to capture all analyses with basic information, complemented with a detailed submission form for full information. The CMS data aggregation system (DAS) is interfaced to the deposit form to assist in filling in exact dataset names used in the analysis to ensure searchability. Efforts are ongoing to describe physics content for an intelligent retrieval, and to interface with container solutions for full reproducibility for selected test cases.

It is shown that self-similar features of jet cross-sections manifested by the z-scaling give strong restriction on the scaling function ψ(z) at high z. New results on energy and angular independence and asymptotic behavior of ψ(z) are discussed. The obtained results are considered as confirmation of self-similarity of jet production, fractality of hadron structure and locality of constituent interactions at small scales.

Abstract:

Purpose This paper aims to investigate if the collaboration intensity of the company with local and international stakeholders facilitates the attracting of venture capital (VC) financing. The reputation of the company was incorporated as a factor, which can potentially influence investment decision-making. The study also aims to make a cross-national comparison of new ventures financing in two innovation regions – Chinese Zhongguancun and American Silicon Valley. Design/methodology/approach Quantitative methodology involving data gathered from 176 venture-backed as well as non-venture backed SME located in Chinese Zhongguancun and American Silicon Valley was applied. The data has been gathered through a survey. A logistic regression model has been adopted to test the hypotheses and explore relationships among concerned variables. Findings The results spotlight that collaboration intensity with the company’s domestic stakeholders could enhance the attractiveness of the company for external investments. Collaboration intensity with foreign stakeholders increases the likelihood of acquiring financial support only for Chinese companies. For American companies, the reputation of their stakeholders did not show a significant effect. However, positive reputation acquired from the Chinese company’s stakeholders enhances the chance of getting funding and moderates the investment effect of collaboration intensity with domestic stakeholders. Originality/value This paper unfolds that the network strength and the reputation of the SME could play the role in getting VC investment. The results are shown in two different contexts (Silicon Valley in the USA and Zhongguancun in China), characterizing the completely different cultural, legal, institutional and operating environments.

We study the inclusive hadroproduction of B0, B+ and [Formula: see text] mesons at leading order in the Parton Reggeization Approach using the universal fragmentation functions extracted from the combined e+e- annihilation data from CERN LEP1 and SLAC SLC colliders. We have described B-meson transverse momentum distributions measured in the central region of rapidity by the CDF Collaboration at Fermilab Tevatron and CMS Collaboration at LHC within uncertainties and without free parameters, applying Kimber–Martin–Ryskin unintegrated gluon distribution function in a proton. The forward B-meson production (2.0<y<4.5) measured by the LHCb Collaboration also has been studied and expected disagreement between our theoretical predictions and data has been obtained.

Abstract:

The contribution of one [Formula: see text] loop to the decay of the Higgs particle into two gammas is recalculated. Since this matrix element is finite in the standard model, it should be calculated in a straightforward way without artifacts such as regularization or ghosts. The result of the present calculation differs from the previous one, giving a Higgs decay rate smaller by a factor of 2 in the mass range of physical interest. In view of the results from the ATLAS Collaboration and the CMS Collaboration, this leads to possible far-reaching experimental consequences.

Abstract:

Abstract The High Luminosity Phase of the CERN Large Hadron Collider (HL-LHC) will require an extensive upgrade of the CMS Inner Tracking system based on high radiation tolerant silicon pixel sensors capable of withstanding fluences up to 23 × 1015 neq/cm2 (1 MeV equivalent neutrons). Thin planar and 3D pixel sensors have been recently selected by CMS to be installed in the upgraded pixel tracker. Thanks to their structure, the 3D pixel sensors have some advantages with respect to planar ones, and are presently more suitable candidates for the innermost layer of the tracker. In this presentation results obtained with FBK planar and FBK 3D sensors readout by prototype read-out chip RD53A will be shown. Both sensor types have 25 × 100 μm2 pitch and 150 μm thickness, and they were manufactured in collaboration with INFN. The sensors readout by the chip were irradiated to several fluences up to the one foreseen for HL-LHC. The analysis of collected data shows very high hit detection efficiency and good spatial resolution as measured after irradiation.

Abstract:

Los Alamos National Laboratory (LANL) has extensive and diverse activities and programs in materials science and engineering. The Center for Materials Science (CMS) was established to promote scientific collaboration and scientific excellence in materials research and engineering throughout the Laboratory and with individuals and institutions outside the Laboratory. The Center's objective is to enhance the Laboratory's materials science and technology contributions to the nation's defense, energy, and scientific missions.Consistent with its main objective, Laboratory resources supply the principal funding for CMS programs. Additional funding for individual scientific research programs conducted by CMS members comes directly from outside sources.To carry out its responsibilities, CMS has accepted four demanding missions:1. Build a core group of qualified and established materials scientists and solid state physicists.2. Promote and support top-quality, interdisciplinary materials research programs at Los Alamos.3. Strengthen the interactions of materials scientists at Los Alamos with the external materials science community.4. Establish and maintain modern materials research facilities in a readily accessible, central location.The core group of CMS members has a broad charter to advance materials science and technology in directions expected to have long-term impact on LANL's mission. The acting director is Don M. Parkin. In addition to the director, six members presently constitute the CMS. James L. Smith heads an experimental effort in superconductivity.

Abstract:

A new event data format has been designed and prototyped by the CMS collaboration to satisfy the needs of a large fraction of physics analyses (at least 50%) with a per event size of order 1 kB. This new format is more than a factor of 20 smaller than the MINIAOD format and contains only top level information typically used in the last steps of the analysis. The talk will review the current analysis strategy from the point of view of event format in CMS (both skims and formats such as RECO, AOD, MINIAOD, NANOAOD) and will describe the design guidelines for the new NANOAOD format.

Abstract:

The processing needs for the High Luminosity (HL) upgrade for the LHC require the CMS collaboration to harness the computational power available on non-CMS resources, such as High-Performance Computing centers (HPCs). These sites often limit the external network connectivity of their computational nodes. In this paper we describe a strategy in which all network connections of CMS jobs inside a facility are routed to a single point of external network connectivity using a Virtual Private Network (VPN) server by creating virtual network interfaces in the computational nodes. We show that when the computational nodes and the host running the VPN server have the namespaces capability enabled, the setup can run entirely on user space with no other root permissions required. The VPN server host may be a privileged node inside the facility configured for outside network access, or an external service that the nodes are allowed to contact. When namespaces are not enabled at the client side, then the setup falls back to using a SOCKS server instead of virtual network interfaces. We demonstrate the strategy by executing CMS Monte Carlo production requests on opportunistic non-CMS resources at the University of Notre Dame. For these jobs, cvmfs support is tested via fusermount (cvmfsexec), and the native fuse module.

Abstract:

The CMS Collaboration is preparing to build replacement endcap calorimeters for the HL-LHC era. The new high-granularity calorimeter (HGCAL) is, as the name implies, a highly-granular sampling calorimeter with approximately six million silicon sensor channels (≈1.1cm2 or 0.5 cm2 cells) and about 250 thousand channels of scintillator tiles readout with on-tile silicon photomultipliers. The calorimeter is designed to operate in the harsh radiation environment at the HL-LHC, where the average number of interactions per bunch crossing is expected to exceed 140. Besides measuring energy and position of the energy deposits, the electronics is also designed to measure the time of their arrival with a precision in the order of 50 ps. This paper summarises the reasoning and ideas behind the HGCAL, describes the current status of the project, and highlights some of the challenges ahead.

Abstract:

Latest results of searches for heavy Higgs bosons in fermionic final states are presented using the CMS detector at the LHC. Results are based on pp collision data collected at centre-of-mass energies of 8 and 13 TeV which have been interpreted according to different extensions of the Standard Model such as MSSM, 2HDM, and NMSSM. These searches look for evidence of other scalar or pseudoscalar bosons, in addition to the observed SM-like 125 GeV Higgs boson, and set 95% confidence level upper limits in fermionic final states and benchmark models explored. The talk reviews briefly the major results obtained by the CMS Collaboration during Run I, and presents the most recent searches performed during Run II.

Abstract:

Triple-GEM detectors were selected by the CMS Collaboration for instrumenting the high η region of the muon system. This region is characterized by a huge radiation background, mainly composed by neutrons and photons. In this context, a discharge probability test was performed in 2017 at the CHARM facility at CERN, to study the operation of the detector in an environment similar to the one of the CMS muon system. A Geant4 simulation was developed in parallel to the actual test, in order to evaluate the behaviour of the detector. This paper will present this simulation, from the detector geometry implementation to the results obtained in terms of sensitivity and energy deposited into the gas gaps.

Abstract:

Abstract To cope with the challenges posed by the High-Luminosity LHC, the CMS experiment will feature a new silicon tracker. The modules of the upgraded inner tracker are hybrid silicon pixel modules based on a new readout chip, developed by the RD53 collaboration. Compared to the readout chip of the current pixel detector, the RD53 chip is capable of sustaining higher hit rates and radiation levels, as well as enabling the use of serial-powering chains. The qualification of the latest version of this chip (RD53B) is underway, and it will lead to the final version of the readout chip to be used in the CMS inner tracker during the HL-LHC. First digital modules featuring the RD53B-CMS chip have been assembled in 2022 (the term digital module denotes a module assembly with readout chips, but without sensors bonded to them). This contribution presents results of tests on these first prototype modules.

Abstract:

Abstract The high-luminosity LHC (HL-LHC) upgrade is presenting new challenges for particle detector technologies. In the CMS muon system gaseous detectors, the increase in luminosity will produce a particle background ten times higher than at the LHC. To cope with the high rate environment and maintain current performance, the triple-gas electron multiplier technology is a promising candidate for high-rate capable detectors for the CMS-ME0 upgrade project in the innermost region of the forward muon spectrometer of the CMS experiment. An intense R&D and prototyping phase is currently ongoing to prove that such technology meets the stringent performance requirements of highly efficient particle detection in the harsh background environment expected in the innermost ME0 region. Here, we describe the recent rate capability studies of triple-GEM detectors operated with an Ar/CO2 (70/30) gas mixture at an effective gas gain of 2 × 104 by using a high intensity 22 keV X-ray generator. Moreover, we present a novel foil design based on double-sided segmented GEM-foils, high voltage power distribution and filtering, which the CMS muon collaboration adopted for realization of the CMS-ME0 project, and their impact on the performance of the detector in the light of new rate capability studies, with a summary of the ongoing R&D activities.

Abstract:

A recent search for the lepton flavor violating (LFV) decays of the Higgs boson, performed by CMS collaboration, reports an interesting deviation from the Standard Model (SM). The search conducted in the channel [Formula: see text] and [Formula: see text] shows an excess of 2.4[Formula: see text] signal events with 19.6 fb[Formula: see text] data at a center-of-mass energy [Formula: see text] = 8 TeV. On the other hand, a search performed by CMS collaboration for the SM Higgs boson produced in association with a top quark pair [Formula: see text] also showed an excess in the same-sign dimuon final state. In this work, we try to find out if these two seemingly uncorrelated excesses are related or not. Our analysis reveals that a LFV Higgs decay [Formula: see text] can partially explain the excess in the same-sign dimuon final state in the [Formula: see text] search, infact brings down the excess well within 2[Formula: see text] error of the SM expectation. Probing such non-standard Higgs boson decay is of interest and might contain hints of new physics at the electroweak scale.
