Centrality dependence of charmed-meson photoproduction in ultrarelativistic heavy ion collisions

Abstract

We calculate the centrality dependence of inclusive cross section of large-pT charmed-meson ($D^0$, $D^{\ast }$, $D^{\ast +}$, and $D_s^{+}$) from heavy quark fragmentation by the hard photoproduction processes for the nucleus-nucleus collisions in ultrarelativistic heavy ion collisions. The numerical results indicate that the modification of the hard photoproduction processes cannot be negligible for the charmed-meson production in Au-Au collisions at Relativistic Heavy Ion Collider (RHIC) and Pb-Pb collisions at Large Hadron Collider (LHC).
