N2 - We investigate possibilities for dynamical P-parity violation in dense baryonmatter in the framework of effective quark models. Dynamical P-parityviolation can appear in models with at least two scalar and two pseudoscalarfields, where both scalar fields are condensed at normal conditions. At specialconfigurations of coupling constants, one of pseudoscalar fields can then alsocondense at some value of baryon density, the phenomenon results in mixingof the scalar and pseudoscalar physical degrees of freedom, hence, giving riseto P-parity violation. We discuss the implications and possible experimentalsignatures for P-parity violation in strong interactions in future experimentswith heavy-ion collisions.
