Initial Vorticities of Quark-Gluon Matter in Heavy-ion Collisions

Abstract

We calculate four types of initial vorticities in Au+Au collisions at energies $\sqrt{S_{NN}}$ = 5--200 GeV using a microscopic transport model PACIAE. Our simulation shows the non-monotonic dependence of the initial vorticities on the collision energies. The energy turning point is around 10-15 GeV for different vorticities but not sensitive to impact parameter.
