摘要：

A multiphase transport (AMPT) model has been successful in explaining a wide range of observables in relativistic heavy ion collisions. In this work, we implement a newer set of free proton parton distribution functions and an impact parameter-dependent nuclear shadowing in the AMPT model. After refitting the parameters of the two-component initial condition model to the experimental data on pp and pp¯ total and inelastic cross sections from s∼ 4 GeV to 13 TeV, we study particle productions in pp and AA collisions. We show that the updated AM...
