Abstract

Ward identities are set up for three-point functions obeying

SU (3) \times SU (3)

chiral algebra. Assuming single-particle dominance and simple momentum dependence of the vertex functions, decay widths of the

K^{*}

,

Q

, and

φ

mesons are obtained with all the mesons on the mass shell. Further, within this scheme, momentum-dependent

K_{l 3}

-decay form factors are also obtained. Our results are in good agreement with experiments.
