The minimal fermionic model of electroweak baryogenesis
A bstractWe present the minimal model of electroweak baryogenesis induced by fermions. The model consists of an extension of the Standard Model with one electroweak singlet fermion and one pair of
Higgs couplings and electroweak phase transition
A bstractWe argue that extensions of the Standard Model (SM) with a strongly first-order electroweak phase transition generically predict significant deviations of the Higgs couplings to gluons,
Electroweak baryogenesis and dark matter with an approximate R-symmetry
A bstractIt is well known that R-symmetric models dramatically alleviate the SUSY flavor and CP problems. We study particular modifications of existing R-symmetric models which share the solution to
The dark side of the electroweak phase transition
Recent data from cosmic ray experiments may be explained by a new GeV scale of physics. In addition the fine-tuning of supersymmetric models may be alleviated by new $ \mathcal{O}\left( {\text{GeV}}
125 GeV Higgs boson and electroweak phase transition model classes
Recently, the ATLAS and CMS detectors have discovered a bosonic particle which, to a reasonable degree of statistical uncertainty, fits the profile of the Standard Model Higgs. One obvious
On the Higgs fit and electroweak phase transition
A bstractWe consider the Higgs portal through which light scalars contribute both to the Higgs production and decay and Higgs effective potential at finite temperature via quantum loops. The positive
Electroweak phase transition and LHC signatures in the singlet Majoron model
We reconsider the strength of the electroweak phase transition in the singlet Majoron extension of the Standard Model, with a low ( TeV) scale of the singlet VEV. A strongly first order phase
Effective theory for electroweak doublet dark matter
We perform a detailed study of an effective field theory which includes the Standard Model particle content extended by a pair of Weyl fermionic SU(2)-doublets with opposite hypercharges. A discrete
Probing the Electroweak Phase Transition with Higgs Factories and Gravitational Waves
After the discovery of the Higgs boson, understanding the nature of electroweak symmetry breaking and the associated electroweak phase transition has become the most pressing question in particle
Probing the electroweak phase transition at the LHC
We study the correlation between the value of the triple Higgs coupling and the nature of the electroweak phase transition. We use an effective potential approach, including higher order,


Electroweak baryogenesis and dark matter in a minimal extension of the MSSM
We examine the possibility of electroweak baryogenesis and dark matter in the nMSSM, a minimal extension of the MSSM with a singlet field. This extension avoids the usual domain wall problem of the

The baryon density which may be produced during the electroweak phase transition in supersymmetric models is computed, taking into account the previously neglected effects of transport, strong and

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.
Supersymmetric electroweak baryogenesis
We re-examine the generation of the baryon asymmetry in the minimal supersymmetric standard model (MSSM) during the electroweak phase transition. We find that the dominant source for baryogenesis
Dark matter, light top squarks, and electroweak baryogenesis
We examine the neutralino relic density in the presence of a light top squark, such as the one required for the realization of the electroweak baryogenesis mechanism, within the minimal
