Determination of impact parameter in high-energy heavy-ion collisions via deep learning

Pei Xiang, Yuan-Sheng Zhao, Xu-Guang Huang

In this study, Au+Au collisions with the impact parameter of $0\le b\le 12.5$ fm at $\sqrt{s_{NN}}=200$ GeV are simulated by the AMPT model to provide the preliminary final-s…
