Description
The measurement of identified charged hadron production at mid-rapidity (|y| < 0.5) performed with the ALICE experiment is resented for PbPb collisions at a nucleon-nucleon c.m. energy of 2.76 TeV. The transverse momentum spectra of charged pions, kaons, protons and antiprotons are measured from 200 MeV/c up to 3 GeV/c for pions and kaons and from 400 MeV/c up to 5 GeV/c for protons and antiprotons using the dE/dx and the time-of-flight particle-identification techniques. Preliminary results on charged hadron production yields and particle ratios are reported as a function of pT and collision centrality. Finally, the results are discussed in terms of hydrodynamics-inspired models and compared with published RHIC data in Au泡u collisions at c.m. energy of 200 GeV per nucleon pair and Monte Carlo predictions.
