Description
ALICE (A Large Ion Collider Experiment), one of the four main experiments at the Large Hadron Collider (LHC), was designed and built to perform dedicated research on heavy-ion collisions to study the Quark-Gluon Plasma (QGP), a deconfined state of strongly interacting QCD matter.
As heavy flavours are produced on a very short time-scale in the initial hard scattering processes, they can be used to characterize the hot and dense medium formed in high-energy heavy-ion collisions through their modified yield as compared to pp collisions. In particular, the production c-cbar bound states was proposed as a thermometer of the created medium.
In ALICE, charmonium production is measured via the dielectron and dimuon decay channels at central (|y| < 0.9) and forward (2.5 < y < 4) rapidity, respectively.
In this talk, final results on charmonium production in Pb-Pb collisions at sqrt{s_{NN}} = 2.76 TeV will be presented and compared to theoretical models, with emphasis on the measurements at forward rapidity using the Muon Spectrometer.
