Abstract:

The relation between masses and decay constants of D- and F-mesons is discussed within the framework of broken chiral SU(4)×SU(4) symmetry in the quartet model. Given the mass of D-mesons, the F⁺-meson mass depends sensitively on the ratio of their leptonic decay constants f_D and f_F. A plausible argument is given to infer a near equality of f_D, f_F and f_π, in contrast with the large f_K/f_π ratio ∼1.28). In addition, some comments are made on the bare mass counting mass formula for the vector mesons including F^+*-mesons.
