Abstract : We report on the first measurement of inclusive J/Psi elliptic flow, v2, in heavy-ion collisions at the LHC. The measurement is performed with the ALICE detector in Pb-Pb collisions at sqrt(sNN) = 2.76 TeV in the rapidity range 2.5 < y < 4.0. The dependence of the J/Psi v2 on the collision centrality and on the J/Psi transverse momentum is studied in the range 0 <= pT < 10 GeV/c. For semi-central Pb-Pb collisions at sqrt(sNN) = 2.76 TeV, an indication of non-zero v2 is observed with a maximum value of v2 = 0.116+/-0.046(stat.)+/-0.029(syst.) for J/Psi in the transverse momentum range 2 <= pT < 4 GeV/c. The elliptic flow measurement complements the previously reported ALICE results on the inclusive J/Psi nuclear modification factor and favors the scenario of a significant fraction of J/Psi production from charm quarks in a deconfined partonic phase.
