Description
Form factors for hadronic transitions are a leading error source in the theoretical estimate of observables whose experimental measurements might eventually uncover BSM physics.
Two theoretical approaches, depending on the kinematic region, for the determination of hadronic form factors are available, namely LCSR and Lattice QCD.
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, building a bridge between the two theoretical determinations and the recently available data on this decays.
In the talk this new method will be presented, based on the publication "Extracting B --> K* Form Factors from Data" arXiv:1204.4444 in collaboration with Gudrun Hiller.
