摘要：

The decay constants for the D and D(S) mesons, denoted f(D) and f(D(S)) respectively, are equal in the SU(3)(V) limit, as are the hadronic amplitudes for B(S)-B(S)BAR and B0-B0BAR mixing. The leading SU(3)(V) violating contribution to (f(D(S))/f(D)) and to the ratio of hadronic matrix elements relevant for B(S)-B(S)BAR and B0-B0BAR mixing amplitudes are calculated in chiral perturbation theory. We discuss the formalism needed to include both meson and anti-meson fields in the heavy quark effective theory.
