摘要：

In the Framework of T2HDM, we calculated the new physics contributions involving neutral Higgs bosons to the branching ratios of (B) over bar (0)(s,d) --> l(+)l(-) (l = e, mu) decays. Comparing the theoretical predictions with the experimental upper-limits, we found that (a) The data of Br((B) over bar (0)(d) --> l(+)l(-)) give the upper bound on tan beta: tan beta <= 22, while Br((B) over bar (0)(s,d) --> l(+)l(-)) give tan beta <= 12 for fixed delta = 0 degrees, m(H+) = 350 GeV, m(H0) = 160 GeV, m(h0) = 115 GeV and m(A0) = 120 GeV; (b) A light neutral Higgs boson mass m(h0) (m(A0)) less than 50 GeV (120 GeV) is excluded by the data of branching ratios for (B) over bar (0)(s,d) --> l(+)l(-) (l = mu) decays with tan beta = 10; (c). The bounds on m(h0) and tan beta, or m(A0) and tan beta are strongly correlated: a smaller (larger) tan beta means a lighter (heavier) neutral Higgs boson.
