摘要：

Recently we updated a multiphase transport (ampt) model with modern parton distribution functions of nuclei (nPDFs). Here we study open charm production in the updated ampt model and compare to the experimental data from pp and AA collisions over a wide range of collision energies. Besides the update of nPDFs, we removed the transverse momentum cutoff on initial heavy quark productions and also included the resultant heavy flavor cross section into the total minijet cross section in the initial condition as described by the hijing model. We show that the ampt model with these updates provides ...
