Spontaneous CP violation and Non-Abelian Family Symmetry in SUSY
We analyse the properties of generic models based on an SU(3) family symmetry providing a full description of quark charged lepton and neutrino masses and mixing angles. We show that a precise fit of the resulting fermion textures is consistent with CP being spontaneously broken in the flavour sector. The CP violating phases are determined by the scalar potential and we discuss how symmetries r...
متن کاملCP violation in SUSY
CP violation in supersymmetric models is reviewd with focus on explicit CP violation in the MSSM. The topics covered in particular are CP-mixing in the Higgs sector and its measurement at the LHC, CP-odd observables in the gaugino sector at the ILC, EDM constraints, and the neutralino relic density.

متن کاملOn CP Violation in SUSY
We discuss some new features of CP violating and FCNC processes in the low-energy SUSY context distinguishing : i) models where the presence of SUSY does not introduce any new avour structure in addition to the usual CKM mixings of the Standard Model (SUSY avour blindness) and ii) models where the breaking of SUSY and its transmission from the hidden to the observable sector are not avour blind...
متن کاملConstraining SUSY Models with Spontaneous CP-Violation via B → ψKs
We study CP-violating effects in B → ψKs decay within minimal supersymmetric models with spontaneous CP-violation. We find that the CP-asymmetry predicted by the Standard Model in this decay, sin 2β ≥ 0.4, cannot be accommodated in these models without violating the bound on the neutron electric dipole moment. This result holds for NMSSM-like models with an arbitrary number of sterile superfiel...
متن کاملPhases and Cp Violation in Susy
We discuss CP violation in supersymmetric theories and show that CP phenomena can act as a probe of their origins, i.e., compactification and spontaneous supersymmetry breaking. CP violation as a probe of the flavor structure of supersymmetric theories is also discussed. A brief overview is given of several low energy phenomena where CP phases can produce new effects. These include important CP...
