Summary of the 2018 CKM Working Group on Semileptonic and Leptonic b-Hadron Decays

Abstract

A summary of WG II of the CKM 2018 conference on semileptonic and leptonic b-hadron decays is presented. This includes discussions on the CKM matrix element magitudes |Vub| and |Vcb|, lepton universality tests such as R(D∗) and leptonic decays. As is usual for semileptonic and leptonic decays, much discussion is devoted towards the interplay between theoretical QCD calculations and the experimental measurements.
