High pT suppression of Lambda and K0s in Pb-Pb collisions at sqrt(sNN)= 2.76 TeV with ALICE
Abstract
The nuclear modification factors RAA and RCP of Lambda and K0s in Pb-Pb collisions at sqrt(sNN)= 2.76 TeV measured by ALICE at LHC are presented. In central collisions a strong suppression at high pT (pT > 8 GeV/c) with respect to pp collisions is observed. The pT region below is dominated by an enhancement of Lambda over the suppressed K0s. The results are compared to those for charged hadrons and to Lambda from lower collision energies.
