Abstract

A current-algebra result is derived for the slope of the scalar form factor in

K_{l 3}

decay which is valid at all momentum transfers. This theorem is compared with the previous results of Dashen and Weinstein and Dashen, Li, Pagels, and Weinstein. Our analysis indicates that there are large corrections to these previous results at

t = {m_{K}}^{2} + {m_{π}}^{2}
