Using the experimental value of the KL-KS mass difference, the authors derive constraints on charged-Higgs-boson couplings in gauge theories of the weak and electromagnetic interactions. These bounds severely restrict the possible magnitude of charged-Higgs-boson effects in K and D meson decays. The results are based on the observation that charged-Higgs-boson-exchange contributions to K0-K0 mixing are of order 1/MH^2 whereas the corresponding W-boson contribution is only of order mc^2/MW^4.
