Abstract

In the last ten years there has been great progress in calculations of decays of BB and DD mesons, and baryons containing a heavy bb or cc quark. One propelling factor has been the measurement of several anomalies in bsb\to s and bcb\to c transitions, these are one of the only signs of physics beyond the Standard Model. The deviations included measurements of branching ratios, angular observables and lepton universality ratios. Another factor is the exclusive-inclusive discrepancy in the determination of the CKM elements VubV_{ub} and VcbV_{cb}. We will first review recent calculations involving bsb\to s and cuc\to u transitions that could shed light on the neutral current anomalies. We will then summarise the progress the determination of the CKM elements, VubV_{ub} and VcbV_{cb}. Finally we will discuss the current theoretical status and experimental prospects for the lepton universality ratios in bsb\to s and bcb\to c semileptonic decays.
