Abstract

Using appropriate continuity arguments in the

{SU}^{(+)} (3) \otimes {SU}^{(-)} (3)

subgroup space, a new sum rule has been derived for

K_{l 3}

decays. This sum rule incorporates corrections to the soft-pion theorem and contains

K_{l 3}

form factors defined at a point much closer to the physical decay region.
