Lepton-Flavor-Dependent Angular Analysis of $B\to K^\ast \ell^+\ell^-$
Belle Collaboration, S. Wehle, C. Niebuhr, S. Yashchenko et autres
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 performed on a data sample corresponding to an integrated luminosity of $711~\mathrm{fb}^{-1}$ …
