The production of prompt charmed mesons D-0, D+ and D*(+), and their
antiparticles, was measured with the ALICE detector in Pb-Pb collisions
at the centre-of-mass energy per nucleon pair, root s(NN), of 2.76 TeV.
The production yields for rapidity vertical bar y vertical bar < 0.5 are
presented as a function of transverse momentum, p(T), in the interval
1-36 GeV/c for the centrality class 0-10% and in the interval 1-16
GeV/c for the centrality class 30-50%. The nuclear modification factor
R-AA was computed using a proton-proton reference at root s = 2.76 TeV,
based on measurements at root s = 7 TeV and on theoretical calculations.
A maximum suppression by a factor of 5-6 with respect to binary-scaled
pp yields is observed for the most central collisions at p(T) of about
10 GeV/c. A suppression by a factor of about 2-3 persists at the highest
p(T) covered by the measurements. At low p(T) (1-3 GeV/c), the R-AA has
large uncertainties that span the range 0.35 (factor of about 3
suppression) to 1 (no suppression). In all p(T) intervals, the R-AA is
larger in the 30-50% centrality class compared to central collisions.
The D-meson R-AA is also compared with that of charged pions and, at
large p(T), charged hadrons, and with model calculations
