Transverse momentum spectra of identified charged hadrons with the ALICE detector in Pb--Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV
The measurement of identified charged-hadron production at mid-rapidity ($|y| < 0.5$) performed with the ALICE experiment is presented for Pb--Pb collisions at $\sqrt{s_{\rm NN}} = \rm .76 TeV$. The transverse momentum spectra of $\pi^{\pm}$, $K^{\pm}$, $p$ and $\bar{p}$ are measured from 100 MeV...

Sumario: | The measurement of identified charged-hadron production at mid-rapidity ($|y| < 0.5$) performed with the ALICE experiment is presented for Pb--Pb collisions at $\sqrt{s_{\rm NN}} = \rm .76 TeV$. The transverse momentum spectra of $\pi^{\pm}$, $K^{\pm}$, $p$ and $\bar{p}$ are measured from 100 MeV/c up to 3 GeV/c for pions, from 200 MeV/c up to 2 GeV/c for kaons and from 300 MeV/c up to 3 GeV/c for protons and antiprotons using the \emph{dE/dx} and the \emph{time-of-flight} particle-identification techniques. Preliminary results on charged hadron production yields and particle ratios are reported as a function of $p_{T}$ and collision centrality. Finally, the results are discussed in terms of hydrodynamics-inspired models and compared with published RHIC data in Au--Au collisions at $\sqrt{s_{\rm NN}} = \rm 200 GeV$ and predictions for the LHC. |
