Abstract We analyse the constraints on dimension-six Δ F = 1 effective operators in models respecting the MFV hypothesis, both in the one-Higgs doublet case and in the two-Higgs doublet scenario with large tan β . The constraints are derived mainly from the b → s inclusive observables measured at the B factories. The implications of these bounds in view of improved measurements in exclusive and inclusive observables in b → s l + l − and s → d ν ν ¯ transitions are discussed.

New strategies for new physics search in B → K*νν̄, B → Kνν̄ and B → Xsνν̄ decays (2009, result): “these values and our prediction for BR(B! K ) are lower than the ones present in the literature [40, 41 ].”

A similar strong correlation within general MFV models exists [74]. As shown in Fig. 16 deviations from this straight line signal non-CMFV eﬀects present in the m”
Anatomy and phenomenology of FCNC and CPV effects in SUSY theories (2009, result): “Moreover, we also observe that departures from the MFV SUSY expectations for BR(Bd → μμ)/BR(Bs → μ+μ−) and BR(Bs → μμ)/∆Ms/(∆Ms)SM(in both directions with respect to the SM predictions) are also expected in the AKM model, even if the ratio BR(Bd → μμ)/BR(Bs → μ+μ−) stays much closer to the MFV value”
Higgs-mediated FCNCs: natural flavour conservation vs. minimal flavour violation (2010, background): “This universality, which is not aected by the presence of possible avour-blind phases, leads to the strict correlation shown in gure This correlation holds not only for Higgs-mediated amplitudes but, more generally, in the presence of both scalar and V A operators with a MFV structure [ 64 ].”
Composite leptoquarks and anomalies in B-meson decays (2014, background): “Following [47], (but rescaling the bound given there to match the slightly more recent measurement in [42]), the measurement of B(K+ → π+νν) produces a bound (at 95% confidence level) on the real NP coefficient δCνν̄ (defined in [47]) of”
Model-independent constraints on new physics in b → s transitions (2011, methodology): “In our numerical analysis, we use the expressions given in [11], adjusting them to take into account also the primed Wilson coefficients, and treat the uncertainties in the SM predictions as relative errors on the theory predictions.”
