Description

This workshop is the seventh in the series of workshops dedicated to semileptonic flavour changing neutral current b hadron decays, which aims to bring together experts from both experimental and theoretical communities. Semileptonic B decays are sensitive probes for physics beyond the Standard Model. Long standing tensions between Standard Model expectations and measurements have been observed since 2013, including hints for violation of lepton flavour universality. The workshop aims at discussing the observed anomalies, theoretical issues and implications, experimental situation and prospects and interplay between the LHC experiments as well as the Belle-II experiment.
