image and image violation and new thermalization scenario in heavy ion collisions

The violation of local image and image invariance in QCD has been a subject of intense discussions for the last couple of years as a result of very interesting ongoing results coming from RHIC. 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 image and image odd effects in heavy ion collisions analogous to the universal thermal behaviour observed in all other high energy interactions.
