Electroweak baryogenesis in left-right-symmetric models

We explore the possibility of electroweak baryogenesis in left-right-symmetric models with a low scale for the local $B-L$ symmetry breaking. We find that the minimal model cannot generate enough $\frac{n_B}{s}$; one way to rectify the situation is to add a parity-odd real Higgs-singlet field to the model. In this case, we obtain a lower limit on the $W_L-W_R$ mixing parameter $\zeta \ge 0.2{\left(\frac{M_{W_L}}{M_{W_R}}\right)}^2$. We study its phenomenological implications.
