Generation of the Baryon Asymmetry of the Universe within the Left--Right Symmetric Model

Abstract

Fermions scattering off first-order phase transition bubbles, in the framework of $SU(2{)}_L\otimes SU(2{)}_R\otimes U(1)$ models, may generate the Baryon Asymmetry of the Universe (BAU), either at the $LR$-symmetry-breaking scale, or at the weak scale. In the latter case, the baryon asymmetry of the Universe is related to CP violation in the $K_0$--${\bar{K}}_0$ system.
