Proton Collectivity in Au+Au Collisions at $\sqrt{s_{\mathrm{NN}}}=2.4-4.5$~GeV from a Unified Purely Hadronic EOS without QCD Phase Transition

Gao-Feng Wei, Shuang-Jie Liu, Yu-Liang Zhao +2

The nuclear equation of state (EOS) is generally considered to soften in the density range of $2-5$ times the saturation density $\ddot{I}{}_0$. Using a purely hadronic transport model, we…
