The ALICE experiment allows to study hadron production over a wide range of momenta exploiting the performance and capabilities of its dedicated detectors. In this report, the particle-identification detectors and techniques are shortly reviewed. The most recent results on the identified charged hadron spectra and ratios obtained in Pb-Pb collisions at √sNN=2.76 TeV and pp collisions at √s=7 TeV and √s=0.9 TeV are presented. In particular, particle production yields, spectral shapes in transverse momentum (pT) and particle ratios in proton-proton collisions are presented as a function of the collision energy, compared to previous experiments and commonly used Monte Carlo models. Particle pT spectra, yields and ratios in Pb-Pb are measured as a function of the collision centrality and the results are compared with available RHIC data. © 2012 American Institute of Physics.

Abstract
The ALICE experiment allows to study hadron production over a wide range of momenta exploiting the performance and capabilities of its dedicated detectors. In this report, the particle-identification detectors and techniques are shortly reviewed. The most recent results on the identified charged hadron spectra and ratios obtained in Pb-Pb collisions at √sNN=2.76 TeV and pp collisions at √s=7 TeV and √s=0.9 TeV are presented. In particular, particle production yields, spectral shapes in transverse momentum (pT) and particle ratios in proton-proton collisions are presented as a function of the collision energy, compared to previous experiments and commonly used Monte Carlo models. Particle pT spectra, yields and ratios in Pb-Pb are measured as a function of the collision centrality and the results are compared with available RHIC data. © 2012 American Institute of Physics.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
