Lepton-Flavor-Dependent Angular Analysis of $B\to K^{\ast }{\ell }^{+}{\ell }^{-}$

Belle Collaboration, S. Wehle, C. Niebuhr +200

We present a measurement of angular observables and a test of lepton flavor universality in the $B\to K^{\ast }{\ell }^{+}{\ell }^{-}$ decay, where $\ell$ is either $e$ or $\mu$. The analysis is…
