Baryogenesis with Electroweak Symmetry Realised Non-linearly

Abstract

Given the limited precision on the measurement of the Higgs self-coupling and the top Yukawa coupling, the speaker and his research group explore the possibility for anomalous Higgs couplings within the nonlinear realisation of the electroweak symmetry, which admits a CP-violating top-Higgs sector. In such a scenario, the electroweak phase transition may be strongly first order and the additional sources of CP-violation may lead to successful electroweak baryogenesis.
