$$\nu $$ ν Electroweak baryogenesis: the scalar singlet strikes back
Published 2023-08-01“…Abstract We perform a comprehensive scan of the parameter space of a general singlet scalar extension of the Standard Model to identify the regions which can lead to a strong first-order phase transition, as required by the electroweak baryogenesis mechanism. We find that taking into account bubble nucleation is a fundamental constraint on the parameter space and present a conservative and fast estimate for it so as to enable efficient parameter space scanning. …”

Electroweak baryogenesis in the CP-violating two-Higgs doublet model
Published 2023-01-01“…In particular, we analyse the dependence of the obtained BAU on the parameters relevant for successful baryogenesis. Our investigations allow us to pinpoint future directions for improvements both in the computation of the BAU and in possible avenues taken for model building. …”

Simulations of Cold Electroweak Baryogenesis: finding the optimal quench time

A different perspective on the vev insertion approximation for electroweak baryogenesis
Published 2021-09-01“…We calculate the source terms for baryogenesis expanding both the self-energy and propagator to first order in mass insertions, which gives the same results as the usual approach of calculating the self-energy at second order and using zeroth order propagators. …”
