B->K*mumu

Abstract

In the past few years there has been increasing interest in b->sll processes, due to the emergence of several intriguing tensions between measured observables and SM predictions. Of particular interest is the study of angular distributions of such decays, where measurements of angular observables, which carry reduced theory uncertainties, can offer detailed insight on the nature of potential new physics models. A previous measurement of the angular distribution of B0 -> K*0(-> K+ pi-)mumu decays at LHCb, using data collected during Run 1, found a tension at the level of 3 standard deviations with the Standard Model. This seminar will present an update of the angular analysis of these decays, including data collected during 2016. There will also be a brief discussion of prospects for the angular analysis of these decays with the full Run 2 dataset.
