  "abstract": "We extract ratios of $B \\to K^*$ form factors at low hadronic recoil from recent data on $B \\to K^* \\mu^+ \\mu^-$ 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.",
