First-order electroweak phase transition in the standard model with a low cutoff
First-order electroweak phase transition in the standard model with a low cutoff
We study the possibility of a first-order electroweak phase transition due to a dimension-six operator in the effective Higgs potential. In contrast with previous attempts to make the electroweak phase transition strongly first-order as required by electroweak baryogenesis, we do not rely on large one-loop thermally generated cubic Higgs interactions. …
