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

This is the authors' abstract. We don't add key points for this paper.

We calculate the centrality dependence of inclusive cross section of large-pT charmed-meson (D⁰, D*, D*+, and Dₛ⁺) 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).
