Constraining SUSY Models with Spontaneous CP-Violation via B → ψKs
نویسنده
چکیده
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 superfields. Further implications of the scenario are discussed.

Probing Spontaneous CP-Violation in Supersymmetric Models via B-Decays
We study implications of spontaneous CP-violation in minimal susy models for CP-asymmetries in rare B, B̄-decays. In particular, we estimate characteristic values of the angles of the unitarity triangle and show that sizeable CP-violating effects result from B − B̄ mixing only. Significant deviations from the SM predictions are pointed out.
متن کاملElectric dipole moments from spontaneous CP violation in SU(3)-flavoured SUSY
The SUSY flavour problem is deeply related to the origin of flavour and hence to the origin of the SM Yukawa couplings themselves. Since all CP-violation in the SM is restricted to the flavour sector, it is possible that the SUSY CP problem is related to the origin of flavour as well. In this work, we present three variations of an SU(3) flavour model with spontaneous CP violation. Such models ...
متن کاملConstraining New Physics with the CDF Measurement of CP Violation in B → ψKS
Recently, the CDF collaboration has reported a measurement of the CP asymmetry in the B → ψK S decay: a ψK S = 0.79 +0.41 −0.44. We analyze the constraints that follow from this measurement on the size and the phase of contributions from new physics to B − B mixing. Defining the relative phase between the full M 12 amplitude and the Standard Model contribution to be 2θ d , we find a new bound: ...
متن کاملφKS in SUSY GUT with right-handed neutrinos
CP violation in the Bd system is discussed in the supersymmetric grand unified theory (GUT) with the right-handed neutrinos. Above the GUT scale, the right-handed down-type squarks couple to the right-handed neutrinos. Due to the renormalization group effect, flavor violations in the lepton sector may be transfered to the right-handed down-type squark mass matrix, which affects the CP violation...
متن کاملCP violation in supersymmetric models with Hermitian Yukawa couplings and A-terms
We analyse the CP violation in supersymmetric models with Hermitian Yukawa and trilinear couplings. We show that Hermitian Yukawa matrices can be implemented in supersymmetric models with SU(3) flavor symmetry. An important feature of this class of models is that the supersymmetric contributions to the EDM of the neutron and mercury atom are suppressed. In this framework, εK can be saturated by...
