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...

description 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 for new physics beyond the Standard Model or a consequence of underestimated hadronic power corrections, we present a direct comparison of two global fits to the data based on the two different assumptions. In addition, we summarise the possible options to resolve this puzzle in the future.
