Abstract
Using the experimental value of the mass difference, we 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 and meson decays. Our results are based on the observation that charged-Higgs-boson-exchange contributions to mixing are of order whereas the corresponding -boson contribution is only of order .
