Description

The fully differential angular distribution for the rare flavor-changing neutral current decay B → K*0e+e- is studied. The emphasis is placed on accurate treatment of the contribution from the processes B → K*0V with intermediate vector resonances V = ρ(770), ω(782), φ(1020), J/ψ, ψ(2S), decaying into the e+e- pair. The two versions of the vector-meson-dominance model for the transition Vγ are used and tested. The branching ratio, longitudinal polarization fraction of the K*0 meson, transverse asymmetry AT(2) and forward-backward asymmetry are compared with data from BaBar and CDF, and predictions for experiments at LHCb and B factories are made.
