Spontaneous P-parity violation in dense baryon matter

TL;DR

This paper explores the theoretical possibility of spontaneous P-parity violation in dense baryon matter using effective quark models, predicting new phenomena that could be observed in heavy-ion collision experiments.

Contribution

It introduces a novel mechanism for P-parity violation involving scalar and pseudoscalar condensates in dense baryon matter within effective quark models.

Findings

P-parity violation can occur at high baryon densities due to pseudoscalar condensate formation.

Mixing of scalar and pseudoscalar degrees of freedom leads to observable P-violation effects.

Potential experimental signatures in heavy-ion collisions are discussed.

Abstract

We investigate possibilities for dynamical P-parity violation in dense baryon matter in the framework of effective quark models. Dynamical P-parity violation can appear in models with at least two scalar and two pseudoscalar fields, where both scalar fields are condensed at normal conditions. At special configurations of coupling constants, one of pseudoscalar fields can then also condense at some value of baryon density, the phenomenon results in mixing of the scalar and pseudoscalar physical degrees of freedom, hence, giving rise to P-parity violation. We discuss the implications and possible experimental signatures for P-parity violation in strong interactions in future experiments with heavy-ion collisions.
