Scientific paper

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 nB/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 WL-WR mixing parameter ζ>=0.2(MWL/MWR)2. We study its phenomenological implications.
