Abstract

We present the elliptic flow of inclusive J/ψ measured in the µ +µ − channel at forward rapidity (2.5 < y < 4.0), down to zero transverse momentum, in Pb-Pb collisions at √ sNN = 2.76 TeV with the ALICE muon spectrometer. The pT dependence of J/ψ v2 in non-central (20%-60%) Pb-Pb collisions at √ sNN = 2.76 TeV is compared with existing measurements at RHIC and theoretical calculations. The centrality dependence of the pT-integrated elliptic flow, as well as the pT dependence in several finer centrality classes is presented.
