摘要：

We investigate the transition form factors for the B-->K*l(+)l(-) (l = mu, tau) decay in light cone QCD. It is found that the light cone and three-point QCD sum rule analyses for some of the form factors for the decay B-->K*l(+)l(-) lead to absolutely different q(2) dependence. The invariant dilepton mass distributions for the B-->K*mu(+)mu(-) and B-->K*tau(+)tau(-) decays and final lepton longitudinal polarization asymmetry, which includes both short-and long-distance contributions, are also calculated.
