      "title": "Quarkonium production and elliptic flow in small systems measured with ALICE",
      "url": "https://rita.finot.ovh/publications/quarkonia/",
      "body": "Quarkonium production in hadronic collisions provides a unique testing ground for understanding quantum chromodynamics (QCD) since it involves both perturbative and non-perturbative regimes of this theory. A variety of experimental observables, such as the production cross-section, polarization, particle correlations, serve as insights into the phenomenology of the quarkonium production and help constrain the theoretical models. Measurements of quarkonia as a function of multiplicity probe multiple parton interactions (MPI), i.e., several parton-parton interactions occurring in a single hadron-hadron collision. Finally, measurements of the azimuthal correlation structure of emitted particles in high multiplicity pp collisions can probe the existence of collective behaviour in small systems. The ALICE detector can reconstruct inclusive quarkonia over a broad kinematical range, spanning from mid-rapidity up to forward rapidity, and down to zero transverse momentum. In addition, at midrapidity, the non-prompt charmonium contribution can be separated from the prompt contribution. In these proceedings, we present new results on the inclusive, prompt and non-prompt J/ψ production cross sections measured by ALICE in pp collisions at different collision energies. The self-normalized ψ(2S)-to-J/ψ yield ratio measurement is investigated as a function of the charged particle multiplicity in pp collisions at √s = 13. TeV. Finally, the first measurement of the J/ψ elliptic flow (v2) in high multiplicity pp collisions at √s = 13. TeV is presented. Results will be compared to theoretical models.\nView PDF\n"

      "title": "Muon Forward Tracker commissioning and preparation for Run 3 data analysis with ALICE (LHC, CERN)",
      "url": "https://rita.finot.ovh/publications/muon-forward-tracker-phd/",
      "body": "The ALICE detector is designed to study the Quark-Gluon Plasma (QGP), a state in which strongly interacting partonic matter is deconfined in a hot and dense medium. The measurement of quarkonium, an important probe of QGP, is possible with ALICE in two regions: at midrapidity, through their dielectron decays, and at forward rapidity, through their dimuon decays with the muon spectrometer. In order to expand the physics program at the forward rapidity region, the Muon Forward Tracker (MFT) was installed in ALICE during the long shutdown, a period in which upgrades take place to prepare for the nextdata taking period. The work of this thesis focuses first on software developments for MFT commissioning tool and the official detector control system. Then, algorithm development was done for the track matching between the muon spectrometer and the MFT based on machine learning. Once the matching is performed and global muon tracks are extracted, the calculation of the point of closest approach between the muon tracks was required for the separation of prompt and non-prompt J/ψ contributions. Thus, the secondary vertexing algorithm was also developed. Finally, quality assessments for Run 3 simulations were done to prepare for the upcoming data taking. \n"

      "title": "ALICE upgrades during the Large Hadron Collider Long Shutdown 2",
      "url": "https://rita.finot.ovh/publications/alice-upgrade/",
      "body": "A Large Ion Collider Experiment (ALICE) has been conceived and constructed as a heavy-ion experiment at the LHC. During LHC Runs 1 and 2, it has produced a wide range of physics results using all collision systems available at the LHC. In order to best exploit new physics opportunities opening up with the upgraded LHC and new detector technologies, the experiment has undergone a major upgrade during the LHC Long Shutdown 2 (2019–2022). This comprises the move to continuous readout, the complete overhaul of core detectors, as well as a new online event processing farm with a redesigned online-offline software framework. These improvements will allow to record Pb–Pb collisions at rates up to 50 kHz, while ensuring sensitivity for signals without a triggerable signature.\nView PDF\n"

      "url": "https://rita.finot.ovh/publications/alice-fragmentation/",
      "body": "Recent measurements of charm-baryon production in hadronic collisions have questioned the universality of charm-quark fragmentation across different collision systems. In this work the fragmentation of charm quarks into charm baryons is probed, by presenting the first measurement of the longitudinal jet momentum fraction carried by $\\Lambda_c$ baryons in hadronic collisions. The data hints that the fragmentation of charm quarks into charm baryons is softer with respect to charm mesons, as predicted by hadronisation models which include colour correlations beyond leading-colour in the string formation. \nView PDF\n"
