英文摘要 | In this paper we analyze the process B-s-->l(+)l(-) in a type-II two-Higgs-doublet model (2HDM) and the minimal supersymmetric standard model (MSSM). All the leading terms of Wilson coefficients relevant to the process are given in the large tan beta limit. It is shown that the decay width for B-s-->l(+)l(-) depends on all parameters except m(A)o in the 2HDM. The branching ratio of B-s-->mu (+)mu (-) can reach its experimental bound in some large tan beta regions of the parameter space in the MSSM because the amplitude increases as tan(3)beta in the regions. For l = tau, the branching ratio can even reach 10(-4) in the regions. Therefore, the experimental measurements of leptonic decays of B-s could put a constraint on the contributions of neutral Higgs bosons and consequently the parameter space in the MSSM. |
