| dc.description.abstract | SU(3) flavor symmetry allows the decay constants fDs and fDd as well as fBs and fBd to be equal. But due to SU(3) flavor symmetry breaking the ratios fBs/fBd and fDs/fDd are deviated from unity. We have estimated these ratios in the heavy quark effective theory and obtained fBs/fBd = 0·93, fDs/fDd = 0·94 and the double ratio (fBs/fBd)/(fDs/fDd) = 0·99. | |
