CP Violation , Higgs Couplings , and Supersymmetry
Supersymmetric extensions of the standard model generically contain additional sources of CP violation. We discuss how at one loop a potentially large CP violating coupling of the lightest Higgs, h0, to leptons is induced in the minimal supersymmetric standard model (MSSM). The CP violating couplings of h0 in extensions of the MSSM, such as the next-to-minimal supersymmetric standard model (NMS...
متن کاملCP violation in B decays and supersymmetry
CP violation in hadronic B-decays is studied in a definite and well motivated framework for flavour physics and supersymmetry. Possible deviations from the standard model both in mixing and in decay amplitudes are discussed. An attempt is made to describe an experimental strategy for looking at these deviations and for measuring the relevant parameters.
متن کاملCP Violation from Supersymmetry in Hyperon Decays ∗
We point out that in supersymmetric models the direct CP violating asymmetry A(Λ 0 −) in Λ → π − p can be of O(10 −3) in the range to be probed by the current E871 experiment. It was pointed out recently that supersymmetry can generate flavor-changing gluonic dipole operators with sufficiently large coefficients to dominate [1] the observed value [2] of (19.3 ± 2.4) × 10 −4 for ǫ ′ /ǫ. In this ...

متن کاملTwo Lectures on FCNC and CP Violation in Supersymmetry ∗
These two lectures constitute a reappraisal and an update of the status of the Flavour Changing Neutral Current (FCNC) and CP violation issues in supersymmetry. The first lecture discusses these points in the framework of the Minimal Supersymmetric Standard Model (MSSM), while the second one provides an analysis in a generic low-energy supersymmetric extension of the Standard Model. The goal of...
