DESCRIPTION:Speakers: MARTINEZ-GARCIA\, Gines (Laboratoire de Physique Sub
 atomique et des Technologies Associees)\nALICE detector has excellent perf
 ormances to study quarkonium production in\nheavy-ion collisions at the LH
 C collider [1]. In this new energy regime\, charmonium could reveal a priv
 ileged probe to study the properties of the high-density strongly interact
 ing system formed in the early stages of high-energy heavy-ion collisions 
 [2].\nBottomonium resonances will be abundantly produced\, providing new c
 onstrains on theoretical models of quarkonium dissociation in QCD matter [
 1]. Additionally\, ALICE will study quarkonium production in proton-proton
  collisions in which high particle multiplicity events could lead to the f
 ormation of high energy density matter as in heavy ions collisions [3].\nI
 n ALICE [4]\, quarkonium is measured down to pT = 0 via their mu+mu− dec
 ay channels in the ALICE muon spectrometer and via their e+e- in the ALICE
  central barrel. After a short description of the apparatus\, the transver
 se momentum and rapidity distributions of inclusive J/Psi production cross
  section in proton-proton collisions at LHC energies will be presented. We
  will discuss the dependence on charged particle multiplicity of J/Psi yie
 ld in proton-proton collisions at sqrt(s) = 7 TeV.\nThe number of reconstr
