Transverse momentum dependence of D-meson production in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=2.76$ TeV

Abstract

The production of prompt charmed mesons D${}^0$, D${}^{+}$ and D${}^{\ast +}$, and their antiparticles, was measured with the ALICE detector in Pb-Pb collisions at the centre-of-mass energy per nucleon pair, $\sqrt{s_{\mathrm{NN}}}$, of 2.76 TeV. The production yields for rapidity $|y|<0.5$ are presented as a function of transverse momentum, $p_{\mathrm{T}}$, 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 $R_{\mathrm{AA}}$ was computed using a proton-proton reference at $\sqrt{s}=2.76$ TeV, based on measurements at $\sqrt{s}=7$ 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 $p_{\mathrm{T}}$ of about 10 GeV/$c$. A suppression by a factor of about 2-3 persists at the highest $p_{\mathrm{T}}$ covered by the measurements. At low $p_{\mathrm{T}}$ (1-3 GeV/$c$), the $R_{\mathrm{AA}}$ has large uncertainties that span the range 0.35 (factor of about 3 suppression) to 1 (no suppression). In all $p_{\mathrm{T}}$ intervals, the $R_{\mathrm{AA}}$ is larger in the 30-50% centrality class compared to central collisions. The D-meson $R_{\mathrm{AA}}$ is also compared with that of charged pions and, at large $p_{\mathrm{T}}$, charged hadrons, and with model calculations.
