ELECTROWEAK BARYOGENESIS IN LEFT-RIGHT-SYMMETRICAL 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 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 greater-than-or-equal-to 0.2(M(W)L/M(W)R)2. We study its phenomenological implications.
