Higgs-Boson Two-Loop Contributions to Electric Dipole Moments in the MSSM
نویسنده
چکیده
The complete set of Higgs-boson two-loop contributions to electric dipole moments of the electron and neutron is calculated in the minimal supersymmetric standard model. The electric dipole moments are induced by CP-violating trilinear couplings of the ‘CP-odd’ and charged Higgs bosons to the scalar top and bottom quarks. Numerical estimates of the individual two-loop contributions to electric dipole moments are given.

One–loop MSSM Contribution to the Weak Magnetic Dipole Moments of Heavy Fermions
The MSSM predictions at the one-loop level for the weak-magnetic dipole moments of the τ lepton and the b quark are analysed. The entire supersymmetric parameter space is scanned with the usual GUT constraint and common squark and slepton mass parameters. The real part of aτ is dominated by the chargino contribution, being the same order as the SM one or even larger in the high tan β region whe...
متن کاملElectric Dipole Moments in the MSSM Reloaded
We present a detailed study of the Thallium, neutron, Mercury and deuteron electric dipole moments (EDMs) in the CP-violating Minimal Supersymmetric extension of the Standard Model (MSSM). We take into account the complete set of one-loop graphs, the dominant Higgs-mediated two-loop diagrams, the complete CP-odd dimension-six Weinberg operator and the Higgs-mediated four-fermion operators. We i...

We perform a comprehensive study of the dominant twoand higher-loop contributions to the 205Tl, neutron and muon electric dipole moments induced by Higgs bosons, third generation quarks and squarks, charginos and gluinos in the Minimal Supersymmetric Standard Model (MSSM). We find that strong correlations exist among the contributing CP-violating operators, for large stop, gluino and chargino p...
متن کاملElectric Dipole Moments in the MSSM at Large tan β
Within the minimal supersymmetric standard model (MSSM), the large tanβ regime can lead to important modifications in the pattern of CP-violating sources contributing to low energy electric dipole moments (EDMs). In particular, four-fermion CP-violating interactions induced by Higgs exchange should be accounted for alongside the constituent EDMs of quarks and electrons. To this end, we present ...
متن کاملHiggs Boson Decays in the Minimal Supersymmetric Standard Model with Radiative Higgs Sector CP Violation
We re–evaluate the decays of the Higgs bosons in the minimal supersymmetric standard model (MSSM) where the tree-level CP invariance of the Higgs potential is explicitly broken by the loop effects of the third–generation squarks with CP–violating soft–breaking Yukawa interactions. This study is based on the mass matrix of the neutral Higgs bosons that is valid for arbitrary values of all the re...
