Recent progress in decays of b and c hadrons

Aoife Bharucha

Résumé

In the last ten years there has been great progress in calculations of decays of B and D mesons, and baryons containing a heavy b or c quark. One propelling factor has been the measurement of several anomalies in b → s and b → 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 V(ub) and V(cb). We will first review recent calculations involving b → s and c → u transitions that could shed light on the neutral current anomalies. We will then summarise the progress the determination of the CKM elements, V(ub) and V(cb). Finally we will discuss the current theoretical status and experimental prospects for the lepton universality ratios in b → s and b → c semileptonic decays.
