A bstract The electroweak phase transition can be made first order by extending the
Standard Model (SM) Higgs sector with extra scalars. The same new physics can explain the …

A bstract In this work we revisit the existence of a strong first order electroweak phase
transition (SFOEWPT) and recent m W precision measurement in the Type-I and Type-II …

A bstract The existence of a second Higgs doublet in Nature could lead to a cosmological
first order electroweak phase transition and explain the origin of the matter-antimatter …

A bstract We investigate the strength of the electroweak phase transition (EWPT) within the
CP-violating 2-Higgs-Doublet Model (C2HDM). The 2HDM is a simple and well-studied …

A bstract The discovery of the Higgs boson by the LHC experiments ATLAS and CMS has
marked a milestone for particle physics. Yet, there are still many open questions that cannot …

A bstract Higgs sector extensions beyond the Standard Model (BSM) provide additional
sources of CP violation and further scalar states that help to trigger a strong first order …

We discuss first-order electroweak phase transition in models with extended Higgs sectors
for the case with relatively heavy additional scalar bosons. We first show that, by the …

A bstract The nature of the electroweak phase transition in two-Higgs-doublet models is
revisited in light of the recent LHC results. A scan over an extensive region of their …

A bstract It is well-known that type II two Higgs doublet models (2HDMs) can struggle to
facilitate a strong first-order electroweak phase transition in the early universe whilst …

A bstract We study the strong first order electroweak phase transition (SFOEWPT) with the
SO (6)/SO (5) composite Higgs model, whose scalar sector contains one Higgs doublet and …
