Fig. 1. (Color online) The centrality dependence of inclusive cross section of large transverse momentum $D^{0}$ meson production in the nucleus-nucleus collisions at RHIC and LHC energies. The dashed line (blue line) for the initial parton hard scattering processes (LO), the dashed-dotted line (red line) for the inelastic photoproduction processes, and the solid line (black) is for the sum of the above processes. The $D^{0}$ meson data points are from the STAR Collaboration[3] and ALICE Collaboration.[9]
