Description
Heavy quark resonances, produced in high energy heavy-ion collisions,
are important observables for the study of Quantum Chromodynamics (QCD)
interactions at extreme energy-densities. Lattice QCD calculations predict a
phase transition of the nuclear matter to Quark Gluon Plasma
(QGP). The suppression (due to color screening mechanism) or
enhancement (due to regeneration mechanism) of charmonium resonances
(J/$\psi$) have been proposed as a signature of QGP. ALICE has
measured the J/$\psi$ in the forward rapidity region via the dimuon ($\mu^{+}\mu^{-}$)
decay channel in Pb-Pb collisions at $\sqrt{s_{NN}}$ =
2.76~TeV, the result shows less suppression with respect to that
measured at lower energies of SPS and RHIC. The elliptic flow
measurement of J/$\psi$ provides an
important observation to test the degree of thermalization of J/$\psi$
in heavy-ion collisions.
In this talk, the elliptic flow of J/$\psi$ measured in the
forward rapidity (-4.0<y<-2.5) of ALICE via $\mu^{+}\mu^{-}$ decay
channel will be discussed for Pb-Pb collisions at
$\sqrt{s_{NN}}$ = 2.76 TeV. The recent
analysis of the p$_{T}$ integrated flow for different
centrality bin will be presented. We will also discuss differential
flow as function of transverse momentum. The results
will be compared with the previous measurements at RHIC and theoretical
calculations.
