Loop-induced CP violation in the gaugino and Higgsino sectors of supersymmetric theories

We show that the gaugino and Higgsino sectors of supersymmetric theories can naturally acquire observable CP violation through radiative effects which originate from large CP-violating trilinear couplings of the Higgs bosons to the third-generation scalar quarks. These CP-violating loop effects are not attainable by evolving the supersymmetric renormalization-group equations from a higher unifi...

The Effective Theory of the Light Stop Scenario

Electroweak baryogenesis in the minimal supersymmetric extension of the Standard Model may be realized within the light stop scenario, where the right-handed stop mass remains close to the top-quark mass to allow for a sufficiently strong first order electroweak phase transition. All other supersymmetric scalars are much heavier to comply with the present bounds on the Higgs mass and the electr...

Higgs-Boson Two-Loop Contributions to Electric Dipole Moments in the MSSM

The complete set of Higgs-boson two-loop contributions to electric dipole moments of the electron and neutron is calculated in the minimal supersymmetric standard model. The electric dipole moments are induced by CP-violating trilinear couplings of the ‘CP-odd’ and charged Higgs bosons to the scalar top and bottom quarks. Numerical estimates of the individual two-loop contributions to electric ...

Constraints from electric dipole moments on chargino baryogenesis in the minimal supersymmetric standard model

A commonly accepted mechanism of generating baryon asymmetry in the minimal supersymmetric standard model ~MSSM! depends on the CP violating relative phase between the gaugino mass and the Higgsino m term. The direct constraint on this phase comes from the limit of electric dipole moments ~EDM’s! of various light fermions. To avoid such a constraint, a scheme which assumes that the first two ge...

New Two-loop Contributions to Hadronic EDMs in the MSSM

Flavor-changing terms with CP-violating phases in the quark sector may contribute to the hadronic electric dipole moments (EDMs). However, within the Standard Model (SM), the source of CP violation comes from the unique CKM phase, and it turns out that the EDMs are strongly suppressed. This implies that the EDMs are very sensitive to non-minimal flavor violation structures of theories beyond th...
