Abstract

I review the phenomenology of exclusive Bbar -> Kbar pi l⁺ l^- decays, with focus on the intermediate resonant Kbar^*(892) mode. The status of angular observables at both ends of the dilepton mass spectrum is revisited. Constraints on the b -> s Wilson coefficients C₇,C₉,C₁0 based on 2011 data from the B factories, CDF and LHCb are presented.
