Abstract

Heavy-flavor hadron production studies in Pb–Pb collisions at √ sNN = 2.76 TeV with the 2010 and 2011 data samples are presented. The measurements are performed with the ALICE detector in various decay channels and in a wide kinematic range. Heavy-flavor hadrons exhibit a suppression in the most central Pb–Pb collisions that amounts to a factor 3–5 for pT ∼ 8–10 GeV/c. The second harmonic of the azimuthal distribution Fourier decomposition, v2, is non-zero for non-central collisions at intermediate pT (∼ 3 GeV/c).
