Electroweak Baryogenesis in Non-minimal Composite Higgs Models
We address electroweak baryogenesis in the context of composite Higgs models, pointing out that modifications to the Higgs and top quark sectors can play an important role in generating the baryon
Top transport in electroweak baryogenesis
In non-supersymmetric models of electroweak baryogenesis the top quark plays a crucial role. Its CP-violating source term can be calculated in the WKB approximation. We investigate the numerical
Lepton-mediated electroweak baryogenesis
We investigate the impact of the tau and bottom Yukawa couplings on the transport dynamics for electroweak baryogenesis in supersymmetric extensions of the standard model. Although it has generally
Kinetic Approach to Electroweak Baryogenesis
After a short review of baryogenesis mechanisms, we focus on the charge transport mechanism at the electroweak scale, effective at strong electroweak phase transitions. Starting from the one-loop
CP-violation for Electroweak Baryogenesis from Dynamical CKM Matrix
We show that the CKM matrix can be the source of CP violation for electroweak baryogenesis if Yukawa couplings vary at the same time as the Higgs acquires its vacuum expectation value. This offers
Electroweak baryogenesis and the standard model effective field theory
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
Electroweak Baryogenesis in Extensions of the Standard Model
We investigate the generation of the baryon asymmetry in two extensions of the Standard Model; these are the SM with a low cut-off and the two-Higgs-doublet model. Analyzing the thermal potential in
Electroweak baryogenesis in a supersymmetric U(1)' model.
TLDR
The nonlocal EWBG mechanism in the thin wall regime is considered and it is found that within uncertainties the observed baryon number can be generated from the tau lepton contribution, with the secluded sector playing an essential role.

TLDR
A model of electroweak baryogenesis requiring no fine tuning and consistent to scales far above 1 TeV is demonstrated, in which dark matter plays the leading role in creating a CP asymmetry that is the source of the baryon asymmetry.

New source for electroweak baryogenesis in the minimal supersymmetric standard model.
TLDR
This work points out that the current for the orthogonal linear combination, H1+H2, is larger by several orders of magnitude, and finds that large CP-violating angles are required to get a large enough baryon asymmetry.
More about Electroweak Baryogenesis in the Minimal Supersymmetric Standard Model
We compute the baryon asymmetry generated at the electroweak phase transition by the Higgs scalar sector of the minimal supersymmetric standard model. Because of large enhancement effects from low
Supersymmetric Electroweak Phase Transition: Baryogenesis versus Experimental Constraints
We use the two loop effective potential to study the first order electroweak phase transition in the minimial supersymmetric standard model. A global search of the parameter space is made to identify

TLDR
It is found that, in the minimal supersymmetric model, baryo-genesis at the weak scale requires a Higgs boson lighter than about 50--55 GeV, as in the standard model, and this result holds true also when the one-loop radiative corrections are taken into account.

TLDR
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.
Erratum for 'Supersymmetric electroweak baryogenesis'
We correct a numerical error which led to an overestimate of the baryon asymmetry from supersymmetric electroweak baryogenesis in our paper JHEP07(2000)018. Updated dependences of the baryon
