Elliptic flow from pQCD + saturation + hydro model

Abstract

We have previously predicted multiplicities and transverse momentum spectra of hadrons for the most central LHC Pb+Pb collisions at $\sqrt{s_{NN}}=5.5$ TeV using initial state for hydrodynamic evolution from pQCD + final state saturation model. By considering binary collision and wounded nucleon profiles we extend these studies to non-central collisions, and predict the $p_T$ dependence of minimum bias $v_2$ for pions at the LHC. For protons we also show how the $p_T$ dependence of $v_2$ changes from RHIC to the LHC.
