Description

Rare $B$-decays are among the most promising indirect probes for the search for New Physics. In recent years there have been several significant hints for physics beyond the SM in semileptonic $b\to s \ell \ell$ transitions. Interestingly, the analysis of these so-called B anomalies indicate a consistent pattern of lepton flavour non-universality.
We present updated global fits of Wilson coefficients both when only one or two Wilson coefficients are involved as well as in a 20-dimensional fit. Using the new data of the LHCb angular analysis of the $B\to K^* \mu^+ \mu−$ decay we make statistical comparisons to determine whether the most favoured explanation of the anomalies is New Physics or underestimated hadronic effects.
