The decay constants for the D and DS mesons, denoted fD and fDS respectively, are equal in the SU(3)V limit, as are the hadronic amplitudes for BS- BS and B0- B0 mixing. The leading SU(3)V violating contribution to ( fDS / fD ) and to the ratio of hadronic matrix elements relevant for BS- BS and B0- B0 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.
