Description
Ultra-relativistic heavy ion collisions produce strongly interacting matter at high temperature and energy density.
Under such extreme conditions a deconfined partonic phase called Quark-Gluon Plasma (QGP) is formed.
The measurement of quarkonia (charmonia and bottomonia) is expected to provide essential information on the QGP properties.
In pp collisions high precision data serve as crucial test for several competing models of quarkonium hadroproduction and provide the essential baseline for the measurements in AA collisions.
Within the ALICE Muon Spectrometer, quarkonia production can be measured down to zero transverse momentum at forward rapidity (2.5<y<4) via the dimuon decay channel.
The latest results on J/psi and Upsilon production in Pb-Pb
collisions at sqrt(s_NN) = 2.76 TeV will be shown and discussed.
An overview of the most important results obtained in pp collisions at
sqrt(s) = 7 TeV will be also given.
