Spontaneous CP violation in supersymmetric theories.

چکیده
We study the minimal version of the supersymmetric standard model with spontaneous CP breaking. In this model, the KM matrix is real and contributions to ε arise from box diagrams involving squarks. We analyze the region of the parameter space which corresponds to values for ε, ε′/ε and the neutron electric dipole moment (NEDM) in agreement with the experimental data. We show that the CP violating phases must be of O(10−2) and the NEDM lies near its present experimental limit.

Leptonic Cp-violation in Supersymmetric Standard Model
We point out the possibility of spontaneous and hard CP-violation in the scalar potential of R-parity broken supersymmetric Standard Model. The existence of spontaneous CP-violation depends crucially on the Rparity breaking terms in the superpotential and, in addition, on the choice of the soft supersymmetry breaking terms. Unlike in theories with R-parity conservation, it is natural, in the co...
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...
متن کاملSpontaneous CP Violation in Non-Minimal Supersymmetric Models
We study the possibilities of spontaneous CP violation in the Next-to-Minimal Supersymmetric Standard Model with an extra singlet tadpole term in the scalar potential. We calculate the Higgs boson masses and couplings with radiative corrections including dominant two loop terms. We show that it is possible to satisfy the LEP constraints on the Higgs boson spectrum with non-trivial spontaneous C...
متن کاملSpontaneous CP Violation in the Next-to-Minimal Supersymmetric Standard Model Revisited
We re-examine spontaneous CP violation at the tree level in the context of the next-to-minimal supersymmetric standard model (NMSSM) with two Higgs doublets and a gauge singlet field. We analyse the most general Higgs potential without a discrete Z3 symmetry, and derive an upper bound on the mass of the lightest neutral Higgs boson consistent with present experimental data. We investigate, in p...
متن کاملSpontaneous CP violation in the supersymmetric Higgs sector.
Spontaneous CP–violation in the minimal supersymmetric standard model with a gauge singlet and a cubic superpotential is examined. Although the tree–level Higgs potential conserves CP, it is shown that with the inclusion of the one–loop top–quark radiative effects , CP may be broken spontaneously. The CP–violating minimum requires two neutral (h 1 , h 2) and one charged (H ±) Higgs–bosons to be...
