重离子碰撞中的P和CP破坏及新的热化方案

P and CP Violation and New Thermalization Scenario in Heavy Ion Collisions

Ariel R. Zhitnitsky

摘要:

在RHIC上观察到的QCD中局域P和CP不变性的破坏,在过去的几年里一直是一个激烈讨论的主题。另外,一个新的热化方案的重离子碰撞通过事件视界作为Unruh效应的表现,也被提出。在本文中,我们认为,这两个,天真无关的现象,实际上是同一枚硬币的两面,因为它们深深植根于相同的基本物理与QCD的一些非常重要的拓扑特征。我们制定了普适性猜想的P和CP奇效应在重离子碰撞类似于所有其他高能相互作用中观察到的普遍的热行为。

英文摘要:

The violation of local P and CP invariance in QCD, as it is observed at RHIC, has been a subject of intense discussions for the last couple of years.Separately, a new thermalization scenario for heavy ion collisions through the event horizon as a manifestation of the Unruh effect, has been also suggested. In this paper we argue that these two, naively unrelated phenomena, are actually two sides of the same coin as they are deeply rooted into the same fundamental physics related to some very nontrivial topological features of QCD. We formulate the universality conjecture for P and CP odd effects in heavy ion collisions analogous to the universal thermal behaviour observed in all other high energy interactions.
