Baryogenesis in the MSSM, nMSSM and NMSSM / Huber, Stephan J. (CERN) ; Konstandin, Thomas (Royal Inst. Tech., Stockholm) ; Prokopec, Tomislav (Utrecht U.) ; Schmidt, Michael G. (Heidelberg U.)
We compare electroweak baryogenesis in the MSSM, nMSSM and NMSSM. We comment on the different sources of CP violation, the phase transition and constraints from EDM measurements..

Electroweak Baryogenesis in a Two-Higgs Doublet Model / Huber, Stephan J. (CERN)
Electroweak baryogenesis fails in the SM because of too small CP violation and the lack of a strong first-order phase transition. It has been shown that supersymmetric models allow for successful baryogenesis, where the Higgsinos play an important role in the transport processes that generate the asymmetry. [...]

Numerical Approach to Multi Dimensional Phase Transitions / Konstandin, Thomas (Royal Inst. Tech., Stockholm) ; Huber, Stephan J. (CERN)
We present an algorithm to analyze numerically the bounce solution of first-order phase transitions. Our approach is well suited to treat phase transitions with several fields. [...]

Baryogenesis with Superheavy Squarks / Huber, Stephan J. (CERN)
We consider a setup where R-parity is violated in the framework of split supersymmetry. The out-of-equilibrium decays of heavy squarks successfully lead to the generation of a baryon asymmetry. [...]

The Baryon asymmetry in the Standard Model with a low cut-off / Bodeker, Dietrich (Bielefeld U.) ; Fromme, Lars (Bielefeld U.) ; Huber, Stephan J. (CERN) ; Seniuch, Michael (Bielefeld U.)
We study the generation of the baryon asymmetry in a variant of the standard model, where the Higgs field is stabilized by a dimension-six interaction. Analyzing the one-loop potential, we find a strong first order electroweak phase transition for Higgs masses up to at least 170 GeV. [...]
