| Description: | At the end of 2015, the LHCb collaboration has recorded the first collisions induced by the LHC proton and lead beams on a fixed target (gaseous targets). Such data will allow a thorough test, for the first time, of the colour screening mechanism predicted by lattice QCD (when producing a quark-gluon plasma in heavy-ion collisions).The LHCb detector is optimised for heavy flavour measurements. In particular, it allows extremely accurate measurements of bound states such as D mesons, J/ψ, ψ' and χ considered as very sensitive probes for quark-gluon plasma studies.Thanks to the LHCb SMOG system (System for Measuring the Overlap with Gas), initially intended for luminosity measurements, noble gases such as He, Ne, Ar, can be injected inside the vertex detector VELO (Vertex Locator). Acting as ''fixed targets'' for the LHC beams, they give access to proton-nucleus and nucleus-nucleus collisions at an optimal energy to study the phase transition from normal nuclear matter to a quark-gluon plasma. In 2018 LHCb recorded PbNe collisions at a centre-of-mass energy of 69 GeV, making it possible to study the phase transition when comparing the results to the previously recorded pNe collisions at the same centre-of-mass energy.The work presented in this thesis encompasses the totality of the PbNe data treatment and analysis, from the data-taking, to the data quality determination, the signal extraction and the efficiency computation. In addition, in this thesis the development of a software tool to determine the centrality information of heavy-ion collisions is presented. This tool was developed with PbPb and PbNe data, and is available for usage within the LHCb collaboration. These results allow to make a much more in-depth analysis of the results by studying the behaviour of the J/ψ and D0 production not only in a new system, but in different centrality regimes within the same PbNe system. ; À la fin de l'année 2015, la collaboration LHCb a enregistré les premières collisions induites par les faisceaux de protons et de ... |
