Abstract
The study of formation of heavy quarkonia in relativistic heavy-ion collisions provides important insight into the properties of the produced high-density QCD medium. Lattice QCD studies show sequential suppression of quarkonia states with increasing temperature; which affirms that a full spectroscopy can provide us a thermometer for the matter produced under extreme conditions in relativistic heavy-ion collisions and one of the most direct probes of deconfinement. Muons from the decay of charmonium resonances are detected in ALICE experiment in p + p and Pb+Pb collisions with a muon spectrometer, covering the forward rapidity region (2.5 < y < 4). The analysis of the inclusive J/ψ production in the first Pb+Pb data collected in the fall of 2010 at a centre of mass energy of \(\sqrt{s_{\rm NN}}=2.76\) TeV is discussed. Preliminary results on the nuclear modification factor (R AA) and the central to peripheral nuclear modification factor (R CP) are presented.
