Abstract
Transverse momentum (pT) distributions of π±, K±, p and p¯ from Pb-Pb collisions at a center-of-mass energy of sNN=2.76 TeV are compared with corresponding measurements from Au-Au collisions at sNN=0.2 TeV at RHIC. The spectral shapes indicate a strong increase of the radial flow velocity with growing sNN. Integrated hadron yields at mid-rapidity are compared with corresponding measurements from RHIC. Particle yield ratios, including strange hadrons are discussed in terms of thermal model calculations. Nuclear modification factors RAA of identified charged hadrons have been measured as a function of pT for the first time up to transverse momenta of 20 GeV/c.
