摘要：
We obtain the constraints on the Cabibbo-Kobayashi-Maskawa matrix elements and on the charged-Higgs-boson parameters in the two-Higgs-doublet model. Using these we find that the branching ratios for the direct CP-violating contributions to the rare decays K(L) --> pi0e+e- and K(L) --> pi0nunuBAR vary in a wide range. The 90% C.L. upper bounds for the CP-violating branching ratios are significantly enhanced relative to the standard model, which could reach 5 X 10(-11) and 4 X 10(-10), respectively. We also find a possibly large T-violating observable in K+ --> pi+mu+mu-.
