We discuss the large set of observables available from the angular distributions of the decay anti-B --> anti-K*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 Super-LHCb (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.

- B → K∗ℓ+ℓ− decays at large recoil in the Standard Model: a theoretical reappraisal (2015, background): “2 From these coefficients, exploiting the symmetries of the infinite mass limit, one can define “optimized” observables in which the soft form factors cancel out, drastically reducing the theoretical uncertainties [22–24].”
