A bstractWe investigate electroweak baryogenesis within the framework of the Standard Model Effective Field Theory. The Standard Model Lagrangian is supplemented by dimension-six operators that facilitate a strong first-order electroweak phase transition and provide sufficient CP violation. Two explicit scenarios are studied that are related via the classical equations of motion and are therefore identical at leading order in the effective field theory expansion. We demonstrate that formally… Expand

Electroweak Baryogenesis from Temperature-Varying Couplings
The fundamental couplings of the Standard Model are known to vary as a function of energy scale through the Renormalisation Group (RG), and have been measured at the electroweak scale at colliders.Expand

Source terms for electroweak baryogenesis in the vev-insertion approximation beyond leading order
In electroweak baryogenesis the baryon asymmetry of the universe is created during the electroweak phase transition. The quantum transport equations governing the dynamics of the plasma particles canExpand
Spontaneous CP-violating electroweak baryogenesis and dark matter from a complex singlet scalar
A bstractCP non-invariance is strongly limited by present experiments, while extra sources of CP-violation are needed for a successful baryogenesis. Motivated by those observations we consider aExpand
Electroweak baryogenesis from light fermion sources: a critical study
Electroweak baryogenesis (EWBG) is sourced by nonstandard CP -violating interactions of the Higgs boson with fermions, usually taken to be the top quark, enhanced by its large Yukawa coupling.Expand

The generality of the arguments rules out any mechanism of electroweak baryogenesis that does not make use of a new source of [ital CP] violation and concludes the QCD damping effects reduce the asymmetry produced to a negligible amount. Expand
