摘要：

We discuss the large set of observables available from the angular distributions of the decay (B) over bar (d) -> (K) over bar*(0)l(+)l(-). 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(b) corrections. Moreover, we discuss their sensitivity to new physics. We explore the experimental sensitivities at LHCb (10 fb(-1)) and SuperLHCb (100 fb(-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(T)((1)) cannot be measured at the LHCb experiment or at future B factory experiments as it requires a measurement of the spin of the final state particles.
