“…This effect in the MSSM at large tan β was pointed out for the quarks in [253,254] and for the leptons in [255]; the CKM matrix also receives finite radiative corrections, as discussed in [256]. The Higgs-mediated FCNC contributions also have a unique feature: they do not decouple when the superpartner masses are much larger than the electroweak scale, provided that the Higgs sector remains light.…”

After an introduction recalling the theoretical motivation for low energy (100 GeV to TeV scale) supersymmetry, this review describes the theory and experimental implications of the soft supersymmetry-breaking Lagrangian of the general minimal supersymmetric standard model (MSSM). Extensions to include neutrino masses and nonminimal theories are also discussed. Topics covered include models of supersymmetry breaking, phenomenological constraints from electroweak symmetry breaking, flavor/CP violation, collider searches, and cosmological constraints including dark matter and implications for baryogenesis and inflation.

“…They have been first considered in [5] and subsequently found to increase by orders of magnitude the branching ratios of the rare decays B 0 s,d → µ + µ − [1,2,3,4] and to decrease significantly the B 0 s -B 0 s mass difference ∆M s [6] relative to the expectations based on the SM. Since both these effects are caused by the same neutral Higgs boson mediated FCNC (see figs.…”

Correlation between ΔMs and B0s,d→μ+μ− in supersymmetry at large tanβ

Considering the MSSM with the CKM matrix as the only source of flavour violation and heavy supersymmetric particles at large tan β, we analyze the correlation between the increase of the rates of the decays B 0 s,d → µ + µ − and the suppression of ∆M s , that are caused by the enhanced flavour changing neutral Higgs couplings to down-type quarks. We give analytic formulae for the neutral and charged Higgs couplings to quarks including large tan β resummed corrections in the SU (2) × U (1) limit and comment briefly on the accuracy of this approximation. For 0.8 However, we point out that in the less likely scenario in which the squark mixing is so large that the neutral Higgs contributions dominate ∆M s , the rates for B 0 s,d → µ + µ − increase with increasing ∆M s and the bounds in question are weaker. Violation of all these correlations and bounds would indicate new sources of flavour violation.

“…The minimal supersymmetric SM (MSSM) with large ratio tan β of the Higgs vacuum expectation values and no new sources of flavour violation in the supersymmetry-breaking Lagrangian is an example of such a minimally flavour-violating (MFV) theory, which nevertheless may exhibit sizeable differences from the SM due to Higgs exchange. The leptonic B s → µ + µ − and B + → τ + ν τ decays have been extensively studied in this model, as well as meson mixing and B → Dτ ν τ [1,2,3,4,5,6,7,8,9,10,11,12,13]. Higgs exchange also generates scalar four-quark operators, which contribute to non-leptonic B decays.…”

We present an analysis of non-leptonic B decays in the minimally flavour-violating MSSM with large tan β. We relate the Wilson coefficients of the relevant hadronic scalar operators to leptonic observables, showing that the present limits on the B s → µ + µ − and B + → τ + ν τ branching fractions exclude any visible effect in hadronic decays. We study the transverse helicity amplitudes of B → V V decays, which exhibit an enhanced sensitivity to the scalar operators, showing that even though an order one modification relative to the SM is not excluded in some of these amplitudes, they are too small to be detected at B factories.
