Large hadronic power corrections or new physics in the rare decay $B \to K^* \mu^+ \mu^-$ ?
The well-known problem of the unknown power corrections within QCD improved factorisation leaves the interpretation of the so-called LHCb anomalies in the angular observables of B → K$^{∗}$ μ$^{+}$ μ$^{−}$ as an open problem. In order to contribute to the question whether they represent a first sign...
