相对论重离子碰撞第一阶段的普适流

Universal Flow in the First Stage of Relativistic Heavy Ion Collisions

Joshua Vredevoogd, Scott Pratt

摘要:

在相对论性重离子碰撞的最初时刻,爆炸性的集体流在物质达到平衡之前就开始增长。这里发现,只要应力-能量张量是无迹的,早期流是独立的,无论是由场或粒子组成的物质,平衡与否,或是否应力-能量张量是各向同性的。这消除了碰撞早期阶段建模的许多不确定性。

英文摘要:

In the first moments of a relativistic heavy ion collision explosive collective flow begins to grow before the matter has yet equilibrated. Here it is found that as long as the stress-energy tensor is traceless, early flow is independent of whether the matter is composed of fields or particles, equilibrated or not, or whether the stress-energy tensor is isotropic. This eliminates much of the uncertainty in modeling early stages of a collision.
