Abstract
We calculate the elliptic flow of charged particles in Pb-Pb collisions at s=2.76 TeV in relativistic viscous hydrodynamics. The recent data of the ALICE Collaboration on the elliptic flow as function of the centrality can be very well described using the hydrodynamic expansion of a fluid with a small shear viscosity η/s=0.08. The elliptic flow as function of the transverse momentum shows systematic deviations from a hydrodynamic behavior in the small momenta region pâ¥<800 MeV. It indicates that a non-negligible contribution of non-thermalized particles from jet fragmentation is present.
