Study of Lepton Universality at Belle

Abstract

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