Extracting B→K* form factors from data.

We extract ratios of B→K* form factors at low hadronic recoil from recent data on B→K*μ(+)μ(-) 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.
