Étude de la production des quarkonia J/Ψ, Ψ' et ϒ en fonction de la multiplicité de traces chargées dans les collisions proton-proton à 8 TeV au LHC avec l'expérience ALICE

Abstract : One of the main goal of the ALICE experiment at LHC is the study of quarkonia. This particles are probe of the quark-gluon plasma (QGP). Quarkonia production rate is sensitive to the formation of the QGP. However, quarkonia production mechanisms are not completely understood in proton-proton collisions. To improve our comprehension of these mechanisms, quarkonia production as a function of charged particles was proposed as a new observable. In this report, I will discuss the measurement of quarkonia production as a function of charged particle multiplicity in pp collisions at ps = 8 TeV. Systematic uncertainties due to the signal extraction via fit on di-muon invariant mass spectrum are studied.
