Summary of the CKM 2023 Working Group on $V_{ub}$, $V_{cb}$ and semileptonic/leptonic B decays including $\tau$

Abstract

This work summarizes recent results, both theoretical and experimental, in $B$-meson leptonic and semileptonic decays and metrology of $V_{ub}$ and $V_{cb}$, which were presented at the CKM 2023 workshop. We place these results in context and discuss future prospects in the field.

Presented at the 12th Workshop on the CKM Unitarity Triangle, 18-22 September 2023, Santiago de Compostela
