The renormalization of chiral perturbation theory is carried out to next-to-next-to-leading order in the meson sector. We calculate the divergent part of the generating functional of Green functions of quark currents to O( p 6 ) for chiral SU(n), involving one-and two-loop diagrams. The renormalizat

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 di
