Rare B -> K^* l^+ l^- Decay in Light Cone QCD

高能物理 - 唯象学 2009-10-30 v2

摘要

We investigate the transition formfactors for the B -> K^* l^+ l^- (l = mu, tau) decay in the light cone QCD. It is found that the light cone and 3-point QCD sum rules analyses for some of the formfactors for the decay B -> K^* l^+ l^- lead to absolutely different q2q^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.
