Machine learning the impact parameter in heavy-ion collisions at $\sqrt{s_{\mathrm{NN}}}$ = 4 and 11 GeV: a cross-check study with UrQMD, AMPT, and JAM

Xiaoqing Yue, Guojun Wei, Yongjia Wang +7

By generating heavy-ion collision data with the ultrarelativistic quantum molecular dynamics (UrQMD) model, a multiphase transport (AMPT) model, and the JAM model, the impact param…
