Abstract:

Recent studies are presented demonstrating the important role played by silicon detectors in the discovery of the Higgs boson. CMS is planning to replace it in an extended technical stop of the LHC in the winter of 2016. We present results showing that this replacement will significantly increase the sample of Higgs bosons that will be reconstructed enabling precision studies of this particle.

Abstract:

The discovery of a SM Higgs boson at the LHC brought about great opportunity to investigate the feasibility of a Circular Electron Positron Collider (CEPC) operating at center-of-mass energy of 240 GeV, as a Higgs factory, with designed luminosity of about [Formula: see text]. The CEPC provides a much cleaner collision environment than the LHC, it is ideally suited for studying the properties of Higgs boson with greater precision. Another advantage of the CEPC over the LHC is that the Higgs boson can be detected through the recoil mass method by only reconstructing [Formula: see text] boson decay without examining the Higgs decays. In Concept Design Report (CDR), the circumference of CEPC is 100 km, with two interaction points available for exploring different detector design scenarios and technologies. The baseline design of CEPC detector is an ILD-like concept, with a superconducting solenoid of 3.0 Tesla surrounding the inner silicon detector, TPC tracker detector and the calorimetry system. Time Projection Chambers (TPCs) have been extensively studied and used in many fields, especially in particle physics experiments, including STAR and ALICE. The TPC detector will operate in continuous mode on the circular machine. To fulfill the physics goals of the future circular collider and meet Higgs/[Formula: see text] run, a TPC with excellent performance is required. We have proposed and investigated the ions controlling performance of a novel configuration detector module. The aim of this study is to suppress ion backflow (IBF) continually. In this paper, some update results of the feasibility and limitation on TPC detector technology R&D will be given using the hybrid gaseous detector module.

Abstract:

Abstract The last decade showed the leading role of the Large Hadron Collider (LHC) experiments in particle physics. To fully exploit its physics potential, the significant increase of LHC luminosity is planned. At the High luminosity Phase-II Upgrade (HL-LHC), foreseen for 2027, a peak instantaneous luminosity of 5 × 1034 cm−2, with an integrated luminosity of 3000 fb−1 is expected. The experiments will be subjected to radiation levels up to 2 × 1016 neq/cm2 at the innermost layers of the detectors. Since more than a decade the RD50 collaboration has been conducting a significant R&D program across experimental boundaries to create silicon sensors with adequate radiation tolerance for HL-LHC trackers. HV-CMOS sensors, 3D detectors, and low gain avalanche detectors (LGADs) are important areas of detector research and development. We will discuss the current state of research and development in numerous silicon detector domains, with a focus on 3D and LGAD detectors. We will also discuss the alternatives for detector selection experiments outside of the LHC, using the FCC as an example.

Abstract:

This study presents an overview of the potential of the ATLAS detector at LHC for the observation of the Higgs boson of the minimal supersymmetric Standard Model (MSSM). The expected rates, backgrounds and significances are discussed channel by channel using realistic assumptions for the detector performance. As final results, the ranges of the MSSM parameter space projected on the (mA, tan β) and (mh, tan β) planes, for which the expected significances for the discovery of the different channels exceed a 5σ value, are shown for the ATLAS detector alone and for combined results from the ATLAS and CMS detectors. It is concluded that the combined potential of the two LHC detectors should fully cover the Higgs sector of the MSSM parameter space. The sensitivity of the results to the upper limit of the allowed mass for the lightest Higgs boson is extensively discussed. The direct impact of the SUSY particle sector on such searches is neglected in this paper.

Abstract:

El Large Hadron Collider (LHC) en la Organización Europea para la Investigación Nuclear (CERN), Ginebra, interrumpirá su operación en 2023 para ser mejorado a High Luminosity LHC (HL-LHC) y proporcionar colisiones entre protones con una energı́a en el centro de masa de √s = 14 TeV con una luminosidad de 1035 cm−2 s−1. ATLAS es uno de los experimentos alojados en el LHC que tendrá que ser mejorado para cumplir los nuevos requisitos impuestos por la mayor luminosidad. Las obras de mejora de ATLAS prevén la sustitución del Inner Detector por un detector de trazas interamente de silicio, el Inner Tracker (ITk), con una granularidad más pequeña y una mayor resistencia a la radiación, y la introducción del High Granularity Timing Detector (HGTD), que proporcionará información temporal de las trazas y de los vértices. Combinando las medidas de ITk y HGTD será posible resolver vértices cercanos en el espacio pero con suficiente separación temporal, lo cual mejora las prestaciones de ATLAS. En esta tesis se investigan dos nuevas tecnologı́as de detectores de silicio para aplicaciones en el HGTD y el ITk, la tecnologı́a de Low Gain Avalanche Detector (LGAD) y la de HV-CMOS. La tecnologı́a LGAD consiste en detectores planares de silicio n-on-p con un implante altamente dopado de tipo p debajo del electrodo de tipo n. Originalmente fue desarrollada para detectores de trazas resistentes a la radiación, pero la segmentación del electrodo demostró afectar al mecanismo de multiplicación y no se ha observado ganancia en los primeros dispositivos. Por otro lado, detectores LGAD delgados han mostrado una resolución temporal de aproximadamente 30 ps y fueron elegidos como de base para los sensores del HGTD. Estudios de sensores LGAD, antes y después de la irradiación, se realizaron por primera vez en el contexto de esta tesis. La tecnologı́a HV-CMOS originalmente aspriaba a producir sensores con pı́xel activo, con la ventaja, en comparación con los dispositivos hı́bridos estándar, de poder optar por el acoplamiento capacitivo. Sin embargo, durante el proceso de IyD, resultó claro que los dispositivos monolı́ticos en tecnologı́a HV-CMOS ofrecen las ventajas más prometedoras: una moderada resistencia a la radiación y la reducción de costos. Esta tesis incluye la caracterización de la primera muestra a escala completa de un chip HV-CMOS para el experimento ATLAS. Actualmente, esta tecnologı́a se tiene en cuenta como una opción de inserción para la capa externa del detector de pı́xeles del ITk.
The Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN), Geneva, will interrupt its operation in 2023 to be upgraded to high luminosity (HL-LHC) and provide proton-proton collisions with a center of mass energy of √s = 14 TeV at a luminosity of 1035 cm−2 s−1. ATLAS, one of the two general purpose experiments at the LHC , will have to be upgraded to meet the new requirements given by the larger luminosity. Among other things the ATLAS upgrade foresees the replacement of the Inner Detector with a full silicon Inner Tracker (ITk), with finer granularity and improved radiation tolerance, and the introduction of the High Granularity Timing Detector (HGTD) that will provide timing information of tracks and vertices. Combining the measurements of ITk and HGTD it will be possible to resolve vertices close in space but separated in time, improving the ATLAS reconstruction performance. In this thesis two novel silicon detector technologies are investigated for applications in the HGTD and ITk, the Low Gain Avalanche Detectors (LGAD) and the HV-CMOS technologies. The LGAD technology consists of planar n-on-p silicon detectors with a highly doped p-type implantation underneath the n-type electrode. It was originally developed for radiation hard tracking detectors but the fine segmentation of the electrode proved to affect the charge multiplication mechanism and no gain has been observed on segmented devices. On the other hand, thin LGAD detectors have shown a time resolution of about 30 ps on the detection of minimum ionizing particles and it was chosen as baseline technology for the HGTD sensors. Studies of LGAD sensors, before and after irradiation were first performed in the context of this thesis. The HV-CMOS technology was originally aimed to provide active pixel sensors with the advantage, compared to the standard hybrid devices, of the AC coupling capability. However, during the R&D effort, it become clear that monolithic HV-CMOS devices offered the most promising advantages: moderate radiation hardness and cost reduction. This thesis includes the characterization of the first full scale HV-CMOS chip prototype for the ATLAS experiment. This technology is currently taken into account as a drop-in option for the outer layer of the ITk pixel detector.

Abstract:

The Standard Model is a mathematical description of the very nature of elementary particles and their interactions, now seen as relativistic quantum fields. A key feature of the theory is the Brout-Englert-Higgs mechanism, responsible for the spontaneous symmetry breaking of the underlying gauge symmetry, and which implies the existence of a neutral Higgs particle. Searches for the Higgs boson were conducted at the Large Electron Positron collider until 2000 and are still ongoing at the Tevatron collider, but the particle has not been not observed. In order to better constrain models with an exotic electroweak symmetry breaking sector, a search for a Higgs boson decaying into a W pair is carried out with the ALEPH detector on 453 pb-1 of data collected at center-of-mass energies up to 209 GeV. The analysis is optimized for the many topologies resulting from the six-fermion final state. A lower limit at 105.8 GeV/c² on the Higgs boson mass in a fermiophobic Higgs boson scenario is obtained. The ultimate machine for the Higgs boson discovery is the Large Hadron Collider, which is being built at CERN. In order to evaluate the physics potential of the CMS detector, the WH associated production of a Higgs boson decaying into a W pair is studied. Performances of data acquisition and its sophisticated trigger system, particle identification and event reconstruction are investigated by performing a detailed analysis on simulated data. Three-lepton final states are shown to provide interesting possibilities. For an integrated luminosity of 100 fb-1, a potential signal significance of more than 5ó is obtained in the mass interval between 155 and 178 GeV/c². The corresponding precision on the Higgs boson mass and partial decay width into W pairs are evaluated. This channel also provides one of the very few possible avenues towards the discovery of a fermiophobic Higgs boson below 180 GeV/c². These studies required many original technical developments, that are also presented.

Abstract:

To extend the physics reach of the LHC, upgrades to the accelerator are planned which will increase the integrated annual luminosity by a factor of 10 (to 250 - 300 fb$^{-1}$/ year). This will increase the occupancy and the radiation damage of the inner trackers. To cope with the elevated occupancy, the ATLAS experiment plans to introduce an all silicon inner tracker for use during High Luminosity LHC (HL-LHC) operation. With silicon, the occupancy can be adjusted by using the appropriate pitch for the pixels/micro-strips. Constraints due to high radiation damage mean that only sensors with electrode configuration designed to read out the electron signal (n-in-p and n-in-n) are considered. The work presented within this thesis has been undertaken as part of the CERN-RD50 and ATLAS Upgrade collaborations. The main focus has been, firstly, on the development of radiation hard silicon detectors and the possible exploitation of the charge multiplication effect observed in irradiated silicon detectors that collect charge via electrons. Secondly, the production and optimisation of n-in-p planar pixel detectors designed specifically for ATLASs new Inner Tracker (ITk). The prototype sensors were produced by Micron Semiconductors Ltd, UK.
