Abstract

By making use of current algebra,

K_{l 3}

decay amplitudes are deduced from the

K_{l 4}

decay amplitudes in the generalized Veneziano model. For

K_{l 3}

decays, we predict that

λ_{+} = \frac{{m_{π}}^{2}}{{m_{K^{*}}}^{2}}

and that

ξ (t) = \frac{f^{-} (t)}{f^{+} (t)} = c (t - {m_{K}}^{2}) - \frac{0.009 t}{{m_{K}}^{2}}

, where

c

is a free parameter.
