Heavy flavour measurements in Pb Pb collisions at $\sqrt{s_\mathrm{NN}}$ = 2.76 TeV with the ALICE experiment

International audienceThe ALICE experiment measured the charm and beauty production in the semi-leptonic decay channels (electrons at mid-rapidity and muons at forward rapidities) and the D meson production in the hadronic decay channels at mid-rapidity in lead-lead collisions at √ sNN = 2.76 TeV and proton-proton collisions at √ s = 7 TeV and √ s = 2.76 TeV. The resulting nuclear modification factors will be presented
