CP violation in supersymmetry with universal strength of Yukawa couplings

Original · EN

We analyse the CP problem in the context of a supersymmetric extension of the standard model with universal strength of Yukawa couplings. In these models we find a small amount of CP violation from the usual CKM mechanism and therefore a significant contribution from supersymmetry is required. The electric dipole moments impose severe constraints on the parameter space, forcing the trilinear couplings to be factorizable in matrix form. We find that the LL mass insertions give the dominant gluino contribution to saturate epsilonₖ, while chargino contributions to epsilon'/epsilon are compatible with the experimental results. Due to significant supersymmetric contributions to Bd-Bd mixing, the recent large value of aⱼ/ψₖₛ can be accommodated.
