The Baryon asymmetry in the standard model with a low cut-off
journal contribution
posted on 2023-06-08, 05:28 authored by Dietrich Bödeker, Lars Fromme, Stephan HuberStephan Huber, Michael SeniuchWe study the generation of the baryon asymmetry in a variant of the standard model, where the Higgs field is stabilized by a dimension-six interaction. Analyzing the one-loop potential, we find a strong first order electroweak phase transition for Higgs masses up to at least 170 GeV. Dimension-six operators induce also new sources of CP violation. We compute the baryon asymmetry in the WKB approximation. Novel source terms in the transport equations enhance the generated baryon asymmetry. For a wide range of parameters the model predicts a baryon asymmetry close to the observed value.
