Abstract

The latest LHCb angular analysis of the rare decay B → K ∗ μ + μ − shows some discrepancies from the SM up to the 37σ level There is a consistent new physics explanation of these anomalies while it is also reasonable that these anomalies are just statistical fluctuations and/or a direct consequence of underestimated hadronic uncertainties We briefly discuss possible crosschecks of the various hypotheses with an analysis of the inclusive B → X s ℓ + ℓ − based on the data collected by the B factories Babar and Belle and also based on future opportunities at SuperBelle We also present a global analysis of the latest LHCb data under the hypothesis of Minimal Flavour Violation The latter is an important benchmark scenario for new physics models Any measurements beyond the MFV bounds and relations unambiguously indicate the existence of new flavour structures next to the Yukawa couplings of the Standard Model However if new physics is responsible for these discrepancies we show it is compatible with the MFV hypothesis so no new flavour structures are needed Moreover we analyse the impact of the correlations between the observables based on a Monte Carlo studyThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
