New physics in rare B decays after Moriond 2021
The anomalies in rare B decays endure. We present results of an updated global analysis that takes into account the latest experimental input – in particular the recent results on [Formula: see text] and BR[Formula: see text] – and that qualitatively improves the treatment of theory uncertainties.

description | The anomalies in rare B decays endure. We present results of an updated global analysis that takes into account the latest experimental input – in particular the recent results on [Formula: see text] and BR[Formula: see text] – and that qualitatively improves the treatment of theory uncertainties. Fit results are presented for the Wilson coefficients of four-fermion contact interactions. We find that muon specific Wilson coefficients [Formula: see text] or [Formula: see text] continue to give an excellent description of the data. If only theoretically clean observables are considered, muon specific [Formula: see text] or [Formula: see text] improve over the Standard Model by [Formula: see text] and [Formula: see text] , respectively. In various new physics scenarios we provide predictions for lepton flavor universality observables and CP asymmetries that can be tested with more data. We update our previous combination of ATLAS, CMS, and LHCb data on BR[Formula: see text] and BR[Formula: see text] taking into account the full two-dimensional non-Gaussian experimental likelihoods. |
