Abstract

We discuss the large set of observables available from the angular distributions of the decay {bar B}{sub d} {yields} {bar K}*{sup 0}{ell}{sup +}{ell}{sup -}. We present a NLO analysis of all observables based on the QCD factorization approach in the low-dilepton mass region and an estimate of {Lambda}/m{sub b} corrections. Moreover, we discuss their sensitivity to new physics. We explore the experimental sensitivities at LHCb (10 fb{sup -1}) and SuperLHCb (100 fb{sup -1}) based on a full-angular fit method and explore the sensitivity to right handed currents. We also show that the previously discussed transversity amplitude A{sub T}{sup (1)} cannot be measured at the LHCb experiment or at future B factory experiments as it requires a measu...
