Extracting $B\to K^{\ast }$ Form Factors from Data

Abstract

We extract ratios of $B\to K^{\ast }$ form factors at low hadronic recoil from recent data on $B\to K^{\ast }{\mu }^{+}{\mu }^{-}$ decays in a model-independent way. The presented method will improve in the future with further (angular) studies in semileptonic rare B-decays and advance our understanding of form factors, which are important inputs in precision tests of the Standard Model.
