On the slope of the scalar K$_{l3}$ decay form factor
Discusses a mechanism, based on exact threshold theorems in the limit of SU(2)*SU(2) symmetry, which can be used to estimate a certain suppression of the scalar K/sub l3/ decay form factor at low momentum transfers, while maintaining the validity of the Callan-Treiman relation. (6 refs).
