Abstract

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.

重离子碰撞中夸克胶子物质的初始涡度
我们利用微观输运模型 PACIAE 计算了能量 SNN=5-200GeV 时 Au+Au 碰撞中的四种初始涡度。我们的模拟显示了初始涡度对碰撞能量的非单调依赖性。对于不同的涡度,能量转折点在 10-15GeV 左右,但对碰撞参数并不敏感。
