英文摘要	Decay rate, forward-backward asymmetry and polarization asymmetries of the final state leptons in B -> K-1 tau(+)tau(-), where K-1 is the axial vector meson, are calculated in the standard model and in the universal extra dimension (UED) model. The sensitivity of the observables to the compactification radius R, the only unknown parameter in the UED model, is studied. Finally, the helicity fractions of the final state K-1 are calculated and their dependence on the compactification radius is discussed. This analysis of the helicity fraction is briefly extended to B -> K*l(+)l(-) (l = e, mu) and compared with the other approaches existing in the literature.
