摘要
We compute the branching ratio and forward-backward asymmetry (A(FB)) distribution for the rare dileptonic decay B -> K*mu(+)mu(-) for the full range of q(2), the dimuon mass squared, region. For the required form factors, we use nonperturbative inputs as predicted by the anti-de Sitter (AdS)/QCD correspondence. When using the Breit-Wigner model with momentum-dependent decay constants to account for the psi and psi' resonance effects in the nonresonance region of the spectrum, we find our predictions to be in better agreement with the experimental data for the branching ratio.
