Spontaneous P-violation in QCD in extreme conditions

Understand

We investigate the possibility of parity being spontaneously violated in QCD at finite baryon density and temperature.

• The analysis is done for an idealized homogeneous and infinite nuclear matter where the influence of density can be examined with the help of constant chemical potential.
• QCD is approximated by a generalized sigma-model with two isomultiplets of scalars and pseudoscalars.
• The interaction with the chemical potential is introduced via the coupling to constituent quark fields as nucleons are not considered as point-like degrees of freedom in our approach.
