Study of Lepton Universality at Belle

Abstract

The Belle Collaboration presented three recent Belle analyses: The search for $B\rightarrow l\nu\gamma$ ($l = e, \mu$) with improved hadronic tagging, the search for $B\rightarrow \mu \nu_\mu$ with inclusive tagging and the test of lepton universality in $B\rightarrow K^*ll$ ($l = e, \mu$) decays.
