The Study Of Supersymmetric Theories In B?k^?*?l⁺l^-

In the high energy physics,the rare decays of B meson play important roles in measuring the CKM matrix elements,searching for the origin of the CP violation,testing the QCD and the standard model,as well as probing the effects of new physics beyond the standard model.Among those,the semi-leptonic decays induced by the flavor-changing neutral current are of interest,because the new particles will affect the observables by entering loop.In this work,we shall study the B?K(*)l+l-induced by b?sl+l-in the minimal supersymmetry model.The invariant mass spectrum,forward-backward asymmetry,as well as lepton polarizations are analyzed,and 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?+?-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*?+?-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?+?-and B?K*?+?-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.Our results will be tested in the on-going LHCb experiment and the forthcoming Belle-?experiments,which shall help us to searching for the supersymmetry indirectly.
