Abstract:

Abstract The performance of muon tracking, identification, triggering, momentum resolution, and momentum scale has been studied with the CMS detector at the LHC using data collected at √(s NN) = 5.02 TeV in proton-proton (pp) and lead-lead (PbPb) collisions in 2017 and 2018, respectively, and at √(s NN) = 8.16 TeV in proton-lead (pPb) collisions in 2016. Muon efficiencies, momentum resolutions, and momentum scales are compared by focusing on how the muon reconstruction performance varies from relatively small occupancy pp collisions to the larger occupancies of pPb collisions and, finally, to the highest track multiplicity PbPb collisions. We find the efficiencies of muon tracking, identification, and triggering to be above 90% throughout most of the track multiplicity range. The momentum resolution and scale are unaffected by the detector occupancy. The excellent muon reconstruction of the CMS detector enables precision studies across all available collision systems.

Abstract:

Recent results from the CMS Collaboration are presented. These measurements include a full physics program using ultraperipheral collisions such as photon-photon and photon-ion interactions, small collision systems including proton-proton and proton-lead collisions, and many measurements of hadronic ion-ion collisions. The properties of the quark-gluon plasma produced in ion-ion collisions are studied in detail. The measurements examine the number of degrees of freedom of the medium, the strength of jet quenching effects in the medium, the role of heavy flavor in hadronization processes, and more.

Abstract:

The measurement of light-flavour-particle production in small collision systems at the LHC has shown features that resemble phenomena seen in heavy-ion collisions. The historical signatures of the quark–gluon plasma (QGP) formation, such as collective flow and the enhanced production of strange hadrons, were also observed in high-multiplicity proton–proton (pp) and proton–lead (p–Pb) collisions. In this article, new results on lightflavour-particle production measured in high-multiplicity triggered events are presented, reaching charged-particle values of semi-peripheral Pb–Pb collisions. In addition, this paper presents the first Run 3 results on the production of π, K, p, and Ω multi-strange baryons in pp collisions at √S = 13:6 TeV and √S = 900 GeV, the highest and the lowest collision energies at the LHC.

Abstract:

Transverse momentum (mass) spectra of positively and negatively charged pions and of positively and negatively charged kaons, protons, and antiprotons produced at mid-(pseudo)rapidity in various collisions at high energies are analyzed in this work. The experimental data measured in central gold-gold, central lead-lead, and inelastic proton-proton collisions by several international collaborations are studied. The (two-component) standard distribution is used to fit the data and extract the excitation function of effective temperature. Then, the excitation functions of kinetic freeze-out temperature, transverse flow velocity, and initial temperature are obtained. In the considered collisions, the four parameters increase with the increase of collision energy in general, and the kinetic freeze-out temperature appears at the trend of saturation at the top Relativistic Heavy Ion Collider and the Large Hadron Collider.

Abstract:

In high-energy hadron collisions, direct photons can be produced in various processes andare of particular interest to study the hot QCD medium since they escape it without being affected.These proceedings present the latest ALICE experiment results concerning direct photon productionin proton-proton (pp), proton-lead (p–Pb) and lead-lead (Pb–Pb) collisions. All measurements agreewith pQCD calculations at high transverse momentum (pT) and show no direct photon excess at lowpT in small systems while a low-pT signal is found in central Pb–Pb collisions.

Abstract:

The Bc+ meson is observed in lead-lead and proton-proton collisions at a center-of-mass energy per nucleon pair of √SNN = 5.02 TeV, via the Bc+ → (J/ψ → μ+μ−)μ+vμ decay and using 2017 and 2018 data from the CMS detector. The resulting Bc+ nuclear modification factor is measured in two bins of the trimuon transverse momentum and of the collision centrality. Less suppression is observed than for other quarkonia and most open heavy flavour mesons. This first observation of the Bc+ meson in heavy ion collisions will shed light on the interplay of suppression and enhancement mechanisms in the production of heavy-flavor mesons in the quark-gluon plasma.

Abstract:

The transverse momentum spectra of different types of particles, π±, K±, p and p¯, produced at mid-(pseudo)rapidity in different centrality lead–lead (Pb–Pb) collisions at 2.76 TeV; proton–lead (p–Pb) collisions at 5.02 TeV; xenon–xenon (Xe–Xe) collisions at 5.44 TeV; and proton–proton (p–p) collisions at 0.9, 2.76, 5.02, 7 and 13 TeV, were analyzed by the blast-wave model with fluctuations. With the experimental data measured by the ALICE and CMS Collaborations at the Large Hadron Collider (LHC), the kinetic freeze-out temperature, transverse flow velocity and proper time were extracted from fitting the transverse momentum spectra. In nucleus–nucleus (A–A) and proton–nucleus (p–A) collisions, the three parameters decrease with the decrease of event centrality from central to peripheral, indicating higher degrees of excitation, quicker expansion velocities and longer evolution times for central collisions. In p–p collisions, the kinetic freeze-out temperature is nearly invariant with the increase of energy, though the transverse flow velocity and proper time increase slightly, in the considered energy range.

Abstract:

Abstract We describe pair-production models of spin-0 and spin-½ magnetic monopoles and high-electric-charge objects (HECOs) in proton–proton (pp) and heavy-ion collisions, considering both the Drell–Yan (DY) and the photon-fusion processes. In particular, we extend the DY production model of spin-½ HECOs to include Z 0-boson exchange for pp collisions. Furthermore, we explore spin-½ and, for the first time, spin-0 production in ultraperipheral heavy-ion collisions. With matrix element calculations and equivalent photon fluxes implemented in MadGraph5_aMC@NLO, we present leading-order production cross sections of these mechanisms in s = 14 TeV pp collisions and s NN = 5.5 TeV ultraperipheral lead–lead collisions at the LHC. While the mass range accessible in ultraperipheral lead–lead collisions is much lower than that in pp collisions, we find that the theoretical production cross sections are significantly enhanced in the former for masses below 82 GeV.

Abstract:

Abstract The high collision energies reached at the LHC lead to significant production yields of light (anti)hypernuclei in proton–proton (pp), proton–lead (p–Pb) and, in particular, Pb–Pb collisions. The lightest known hypernucleus is the hypertriton, which is a bound state of a proton, a neutron, and a Λ hyperon. It decays weakly with a decay length of a few centimeters. The excellent tracking and particle identification capabilities of the ALICE detector, exploiting the energy loss measurement of the Time Projection Chamber (TPC) and using the Inner Tracking System (ITS) to distinguish between primary and secondary (decay) vertices, allow for the determination of the hypertriton yield across different collision systems, its lifetime, and its binding energy. The latest hypertriton lifetime measurement in Pb–Pb collisions performed in the 2-body decay channel will be presented. This measurement contributes to the solution of the hypertriton lifetime puzzle. In addition, the hypertriton production in different collision systems and at different energies will be compared to model predictions. Due to its low binding energy, and hence to its large size, the hypertriton is the ideal candidate to distinguish between statistical hadronization and coalescence models. With the precision of the presented yield measurements some variants of the aforementioned models can be excluded.

Abstract:

2015 - 2016
La TPMC risulta essere una procedura molto più sofisticata perché lavora in perfetto accordo con le raccomandazioni dei codici normativi visto che rispetta a pieno i criteri di gerarchia. Questi ultimi, infatti, sono fondamentali per evitare meccanismi pericolosi come quello di "softstorey" ma non stifficienti a garantire lo sviluppo della massima capacità dissipativa della struttura. Al fine di offrire una validazione della procedura sono state progettate diverse strutture intelaiate con differenti geometrie e caratteristiche. Per queste sono state condotte sia analisi di push-over che analisi dinamiche incrementali proprio con l 'intento di indagare il reale comportamento al collasso delle strutture progettate. Tutti i risultati ottenuti confermano la capacità della procedura proposta di garantire un meccanismo di collasso di tipo globale. L 'importanza di questa teoria e quindi delle strutture progettate è quella di massimizzare l 'energia sismica dissipata durante l 'evento sismico e quindi la duttilità globale, in quanto, tutte le zone dissipative sono coinvolte nella plasticizzazione. Al contrario, il criterio trave-colonna, suggerito dalle normative, appare solo come un 'approssimazione paragonata con la TPMC e con il suo background teorico. Durante il periodo di studio è stato realizzata un 'interfaccia grafica per il progetto delle strutture intelaiate in cemento armato. Il programma lavora come pre- e post- processo re della routine di calcolo che applica il progetto della struttura mediante il teorema cinematico del collasso plastico. L'obiettivo di tale software è quello difavorire la diffusione della metodologia offrendo la possibilità di progettare in accordo con la TPMC mediante uno strumento che sia di facile utilizzo per tutti i tipi di utenti, anche quelli meno esperti delle tecnologie informatiche.

Abstract:

L'étude de la production des quarks charmés dans les collisions de hautes énergies de noyaux atomiques offre une approche inédite pour l'étude du plasma de quarks et de gluons. La compréhension et la caractérisation de cet état de la matière déconfinée, de prime abord retrouvé dans les systèmes les plus lourds, nécessitent une connaissance fine des systèmes les plus légers, telles que les collisions proton-proton (pp) et proton-plomb (p-Pb). Dans ce manuscrit, nous présentons la mesure de la production des mésons charmés-étranges Ds+, à rapidité centrale, avec les données du run 2 du LHC, recueillies en 2016 par l'expérience ALICE. Deux systèmes sont étudiés : les collisions pp à √s=13 TeV et p-Pb à √sNN=5,02 TeV. La section efficace de production des Ds+, leur abondance relative et leur facteur de modification nucléaire sont mesurés puis comparés à d'autres mesures et à diverses prédictions théoriques. Le résultat p-Pb établit une nouvelle référence pour l'étude des collisions Pb-Pb
The study of the production of charm quarks in high-energy atomic-nucleus collisions offers an genuine approach for the study of the quark-gluon plasma. The understanding and characterisation of this state of deconfined-matter, at first sight created in heaviest systems, require a fine knowledge of lightest systems, such as proton-proton (pp) and proton-lead (p-Pb) collisions. In this manuscript, we present the measurement of the charm-strange mesons Ds+ production, at central rapidity, with the LHC run 2 data, collected in 2016 with the ALICE experiment. Two systems are studied: pp collisions at √s=13 TeV and p-Pb collisions at √sNN=5.02 TeV. The production cross-section of Ds+, their relative abundance and their nuclear modification factor are measured then compared to other measurements and to various theoretical predictions. The p-Pb result establishes a new reference for the study of Pb-Pb collisions

Abstract:

La thèse est effectuée dans le contexte de l’expérience ALICE dédiée à l’étude de la chromodynamique quantique et plus particulièrement du plasma de quarks et de gluons (QGP) grâce aux collisions d’ions lourds ultrarelativistes auprès du LHC au CERN. La thèse porte sur l’étude de la production du méson beau B⁰ (d b̅) via le canal de désintégration B⁰ → (D⁻ → π⁻ K⁺ π⁻) π⁺ dans des collisions proton-Plomb (resp. proton-proton) à une énergie dans le centre de masse √sNN = 5.02 TeV (resp. √s = 13.6 TeV) avec le détecteur ALICE, durant le Run 2 (resp. Run 3) du LHC, dans des domaines de rapidité centrale (|ylab| < 0.5) et d’impulsions transverses faibles à élevées (2 < pT < 24 GeV/c). La première mesure de la section efficace de production des mésons D⁻ (d c̅), issus de la désintégration d’un hadron beau en collisions proton-Plomb à rapidité centrale, permet d’établir le facteur de modification nucléaire de ces mésons en collisions proton-Plomb, fournissant alors une sonde indirecte à l’étude des effets nucléaires froids impactant les mésons B⁰ et dont le QGP ne serait pas responsable. La chaîne d’analyse de ce méson beau, développée durant cette thèse au sein du nouveau logiciel d’ALICE, est également présentée et validée via la mesure du taux de production des mésons B⁰ avec des données simulées. Cette chaîne d’analyse, appliquée à des données issues de collisions proton-proton du Run 3 du LHC, a rendu possible la première observation d’un signal de méson B⁰ via reconstruction topologique complète au sein de la collaboration ALICE. Les résultats obtenus constituent des références nécessaires à la caractérisation des effets engendrés par le QGP sur la production de ces mésons beaux
The thesis is performed in the context of the ALICE experiment dedicated to the study of quantum chromodynamics and especially of the quark-gluon plasma (QGP) through ultrarelativistic heavy ion collisions at the LHC (CERN). The thesis addresses the production of the beauty-meson B⁰ (d b̅) through the decay channel B⁰ → (D⁻ → π⁻ K⁺ π⁻) π⁺ in proton-lead (resp. proton-proton) collisions Version mai 2021 4 / 4 with a center-of-mass energy √sNN = 5.02 TeV (resp. √s = 13.6 TeV) with the ALICE detector, during LHC Run 2 (resp. Run 3), in domains of midrapidity (|ylab| < 0.5) and low to high transverse momentum (2 < pT < 24 GeV/c).The first measurement of the production cross section of D⁻ (d c̅) mesons, originating from a beauty-hadron decay in proton-lead collisions at midrapidity, allows for the establishment of the nuclear modification factor of these mesons, providing an indirect probe towards the study of nuclear effects impacting B⁰ mesons, and not due to QGP. The analysis workflow of this beauty meson, developped during this thesis in new ALICE software, is also presented and validated via measurements of B⁰ mesons production rate in simulated data. This analysis workflow, applied to real data from proton-proton collisions of LHC Run 3, made possible the first observation of B⁰ meson signal via full topological reconstruction in the ALICE collaboration. The results obtained establish necessary references to characterise QGP-induced effects on the beauty-meson production

Abstract:

The spacetime dimensions of the particle source in proton-lead collisions at √sNN = 5.02 TeV are measured with the ATLAS detector at the Large Hadron Collider. Femtoscopic measurements are made from correlation functions built with charged pions identified by their ionization energy loss. The measured HBT radii that represent the source dimensions are presented differentially as a function of centrality, transverse momentum, and rapidity. The effect of jet fragmentation on the two-particle correlation function is studied, and a method using opposite-charge pair data to constrain its contributions to the measured correlations is described. The measured source sizes are substantially larger in more central collisions and are observed to decrease with increasing pair transverse momentum. A correlation of the radii with the local charged-particle density dN/dy is demonstrated. The scaling of the extracted radii with the mean number of participating nucleons is also used to compare a parameterization of an initial-geometry model that allows for fluctuations in the proton cross-section. The cross-term R_ol is measured as a function of rapidity, and a nonzero value is observed that agrees with hydrodynamic predictions. The HBT radii are also shown for central events in intervals of azimuthal angle relative to the 2nd-order event plane, pair transverse momentum, and flow vector magnitude, where the correlation functions are corrected for the event plane resolution. Significant modulations of the transverse HBT radii R_out, R_side, and R_os are observed. The orientation of this modulation is the same as that in heavy-ion collisions, in which they are attributed to hydrodynamic evolution from an elliptic initial geometry. The sign and transverse momentum dependence of these modulations are consistent with a hydrodynamic evolution of a short-lived medium.
