Searching for P- and CP-odd effects in heavy ion collisions

TL;DR

This paper explores the potential for detecting P- and CP-odd effects in heavy ion collisions, proposing observables to identify symmetry breaking and a possible new metastable phase in strong interactions.

Contribution

It introduces a novel approach to identify P- and CP-odd effects in heavy ion collisions through specific observables, suggesting the existence of a metastable phase.

Findings

Proposed observables to detect parity breaking

Identified signatures of a metastable phase

Suggested experimental tests for symmetry violation

Abstract

In this talk we will summarize the main results from our recent work concerning the possibility that a new metastable phase occurs in some heavy ion collisions (HIC). This phase would be characterized by the breaking of two characteristic symmetries of strong interactions; namely P and CP. We investigate the experimental consequences of parity breaking in such a situation and propose suitable observables to elucidate the presence this phenomenon.
