Initial vorticities of quark-gluon matter in heavy-ion collisions

摘要

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