Protecting the primordial baryon asymmetry in the $SU(2{)}_L$ triplet Higgs model compatible with KamLAND and WMAP

Abstract

We find the condition that the primordial baryon asymmetry is not washed out in the $SU(2{)}_L$ triplet Higgs model by solving the Boltzmann equation. We further require that the model is compatible with the recent results of the neutrino oscillation experiments and WMAP, and the constraints on the $\rho$ parameter imposed by the LEP. We finally obtain the allowed region of the parameters in the model.
