Constraints on new physics in MFV models: A model-independent analysis of ΔF=1ΔF=1 processes

We analyse the constraints on dimension-six ΔF=1ΔF=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 tanβtanβ. The constraints are derived mainly from the b→sb→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→sℓ+ℓ−b→sℓ+ℓ− and s→dνν¯ transitions are discussed.
