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

TL;DR

This paper links P and CP violation in QCD observed at RHIC with a new thermalization scenario in heavy ion collisions, proposing they share a common topological origin rooted in fundamental physics.

Contribution

It introduces a conjecture connecting P and CP odd effects with a universal thermal behavior in heavy ion collisions based on topological QCD features.

Findings

P and CP violation and thermalization are connected through topological QCD effects.

A universality conjecture for P and CP odd effects in heavy ion collisions.

Proposes a common fundamental physics origin for observed phenomena.

Abstract

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.
