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

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