Summary of the working group for , and semileptonic/leptonic decays including at CKM 2021

Abstract

A summary of the activities of WG2 at the 2021 CKM conference is presented. This includes discussion of the latest developments regarding the determination of the CKM elements $|V_{cb}|$, $|V_{ub}|$ and measurements of lepton universality with decays involving $\tau$ leptons. Consideration is given to both the theoretical and experimental aspects of the subject
