Query: 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.
