Bounds on the form factor of $K_{l3}$ decay
The author derives bounds on the form factor f(t) of K/sub l3/ decay valid from the origin to the threshold (m/sub pi /+m/sub K/)/sup 2/. If he uses as input the soft-pion theorem on f/sub +or-/(t) and a bound on the propagator Delta (0) of the divergence of the strangeness changing current at zero...
