Abstract

Precision measurements of heavy flavour decays constitute powerful tests of the Standard Model (SM) of particle physics. Rare flavour changing neutral current decays are particularly sensitive probes as they are heavily (loop-)suppressed in the SM. New heavy particles can contribute to these processes through virtual quantum corrections and significantly affect their decay rates and angular observables, thereby allowing to probe New Physics scales well beyond those accessible through direct searches. In this talk I will present the most recent results on the key rare decay B0->K*0mumu from the LHCb Experiment using the Run 1 and 2 data sample. The angular distributions of this decay and its rate are found to be in tension with SM predictions, consistent with tensions seen in other rare b->smumu decays. Finally, I will discuss potential interpretations of these anomalies and give prospects for their clarification in the future.
