High p_T suppression of Lambda and K0s in Pb-Pb collisions at   sqrt(s_NN)= 2.76 TeV with ALICE
  The nuclear modification factors R_AA and R_CP of Lambda and K0s in Pb-Pb collisions at sqrt(s_NN)= 2.76 TeV measured by ALICE at LHC are presented. In central collisions a strong suppression at high p_T (p_T > 8 GeV/c) with respect to pp collisions is observed. The p_T 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.
