D mesons suppression in PbPb collisions at sqrt{s_{NN}} = 2.76 TeV   measured by ALICE
  The measurement of the prompt charm mesons D0, D+, D*+, and their antiparticles, in PbPb collisions at the LHC, at a centre-of-mass energy sqrt{s_{NN}}=2.76 TeV, with the ALICE detector, using 2010 data, is presented. The RAA of the three meson species show a suppression of a factor 3-4, for transverse momenta larger than 5 GeV/c, in the 20% most central collisions. The suppression is reduced for peripheral collisions. The results are compared with those of charged particles, charged pions, and non-prompt Jpsi, and also with theoretical calculations.
