A two - loop contribution to B s → μ + μ − at large tan β in the MSSM

sνν̄ decay in the MSSM : Implication of b → sγ at large tan β

The decay b → sνν̄ is discussed in the minimal supersymmetric standard model with general flavor mixing for squarks, at large tan β. In this case, in addition to the chargino loop contributions which were analyzed in previous studies, tan β-enhanced contributions from the gluino and charged Higgs boson loops might become sizable compared with the standard model contribution, at least in principl...

Enhancement of B ( B̄ d → μ + μ − ) / B ( B̄ s → μ + μ − ) in the MSSM with Minimal Flavour Violation and Large tan β

Neutral Higgs boson contributions to the decays B̄d,s → μ+μ− in the MSSM at large tanβ

It is well known that the Minimal Supersymmetric Standard Model (MSSM) can enhance B (B̄d,s → μ+μ−) by orders of magnitude [1], even if we assume the Cabibbo-Kobayashi-Maskawa (CKM) matrix to be the only source of flavour violation. Of particular interest is the quantity R ≡ B (B̄d → μ+μ−)/B (B̄s → μ+μ−), since (i) the theoretical errors cancel to a large extent, and (ii) it offers a theoretically...

Electric 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 ...
