Direct comparison of global fits to the B -> K* μ+μ- data assuming hadronic corrections or new physics
Abstract
The LHCb measurements on the B -> K*μ+ μ- angular observables have shown slight deviations from their Standard Model predictions. The significance of the deviations in the B -> K*μ+ μ- decay depends on the assumptions on the size of the non-factorisable power corrections. At present, there are no theoretical predictions on the size of these power corrections in order to identify whether the reason behind these anomalies is due to unknown hadronic corrections or New Physics effects. We have performed a statistical comparison of fitting the data to each of the possible explanations.
