Bounds on the $K_{l3}$ scalar form factor from low-energy K$\pi$ phase shift
Upper and lower bounds on the scalar form factor of K/sub l3/ decay are calculated using the analytic properties of the form factor, the experimental low-energy S-wave K pi phase shift, and an estimate of the propagator Delta (t) of the divergence of the strangeness changing current at zero momentum...
