Abstract

SU(3) flavor symmetry allows the decay constantsf D 1 andf D 2 as well asf B 1 andf B 1 to be equal. But due toSU(3) flavor symmetry breaking the ratiosf B 1/f B 2 andf D 1/f D 2 are deviated from unity. We have estimated these ratios in the heavy quark effective theory and obtainedf B 1/f B 2=0.93,f D 1/f D 2=0.94 and the double ratio (f B 1/f B 2)/(f D 1/f D 2)=0.99.
