英文摘要: The invariant mass spectrum, forward-backward asymmetry, and lepton polarizations of the exclusive processes B--> K(K*)l(+)l(-),l=mu,tau are analyzed in a supersymmetric context. Special attention is paid to the effects of neutral Higgs bosons (NHB's). Our analysis shows that the branching ratio of the process B --> K mu (+)mu (-) can be quite largely modified by the effects of neutral Higgs bosons and the forward-backward asymmetry would not vanish. For the process B-->K*mu (+)mu (-), the lepton transverse polarization is quite sensitive to the effects of NHB's, while the invariant mass spectrum, forward-backward asymmetry, and lepton longitudinal polarization are not. For both B-->K tau (+)tau (-) and B-->K*tau (+)tau (-), the effects of NHB's are quite significant. The partial decay widths of these processes are also analyzed, and our analysis manifests that, even taking into account the theoretical uncertainties in calculating weak form factors, the effects of NHB's could make supersymmetry show up.
