Abstract

We use perfect-fluid hydrodynamical model to predict the elliptic flow coefficients in Pb+Pb collisions at the Large Hadron Collider (LHC). The initial state for the hydrodynamical calculation for central A+A collisions is obtained from the perturbative QCD + saturation model. The centrality dependence of the initial state is modeled by the optical Glauber model. We show that the baseline results obtained from the framework are in good agreement with the data from the Relativistic Heavy Ion Collider and show predictions for the p_T spectra and elliptic flow of pions in Pb+Pb collisions at the LHC. Also mass and multiplicity effects are discussed.
