Z2 non-restoration and composite Higgs: singlet-assisted baryogenesis w/o topological defects

Abstract Simple scalar-singlet extensions of the Standard Model with a (spontaneously broken) Z 2 symmetry allow for a strong first order electroweak phase transition, as sought in order to realize electroweak baryogenesis. However they generically also lead to the emergence of phenomenologically pr...
