Description

A careful analysis of $B\to K^*\mu^+\mu^-$ observables should consider the long-distance effects of the resonances in the short-distance dominated region. Here, we take into account the narrow resonance effects in the nonresonance region when calculating the differential decay rate and the forward-backward asymmetry in this decay. In doing so, we use a Breit- Wigner model for the resonances with momentum-dependent decay constants, a model that fits the data on photoproduction and the leptonic width of $\psi$ and $\psi^\prime$ simultaneously
