Abstract

Abstract: The nuclear modification factor, R_AA, of the prompt charmed mesons D⁰, D⁺ and D^∗+, and their antiparticles, was measured with the ALICE detector in Pb-Pb collisions at a centre-of-mass energy sNN=2.76(Formula presented.) TeV in two transverse momentum intervals, 5 <p_T<8 GeV/c and 8 <p_T<16 GeV/c, and in six collision centrality classes. The R_AA shows a maximum suppression of a factor of 5-6 in the 10% most central collisions. The suppression and its centrality dependence are compatible within uncertainties with those of charged pions. A comparison with the R_AA of non-prompt J/ψ from B meson decays, measured by the CMS Collaboration, hints at a larger suppression of D mesons in the most central collisions.[Figure not available: see fulltext.]
