Topics in electroweak baryogenesis: the sphaleron and t-violation

摘要: Assuming that beyond the standard model physics can be parametrized in terms of high dimensional operators, we examine their effects on energy sphaleron and classical solution gauge Higgs fields. In absence fermions, all six dimension 6 operators which are SU(2) symmetric have a small effect when calculated perturbatively. However, non-perturbatively, one alters boundary conditions equations motion fields involved, another operator gives rise to an abrupt change at but definite quartic coupling.
