✦ Synopsis

K, form factors are studied in an analytic hard-meson approach, using the (8,8) mod;1 of chiral SU(3) @ SU( 3) symmetry breaking. The divergence form factor is required to show resonance behavior near the kappa meson mass. The ensuing resonance conditions are used to express &, , the slope of the divergence form factor and I', , the kappa width, in terms of the kappa mass. A considerable suppression of & below its Callan-Treiman value can be obtained. Comparison is made with a previous analysis of Kzs decay using the (3, 3*) + (3*, 3) model of symmetry breaking. It is suggested that one cannot rule out the (8, 8) model in favor of the (3,3*) + (3*, 3) at present.

K,% form factors are calculated in the single particle approximation to the spectral functions. The so-called sigma terms and current divergences are calculated in the (8, 8) model of chiral symmetry breaking. Comparison with the experimental results and the (3,3\*) + (3\*, 3) model is made.
