✦ Synopsis

K13 form factors are studied in the analytic hard-meson framework. The Gell-Mann-Oakes-Renner model for chiral SL1(3) x SL1(3) symmetry breaking is employed to determine the so called o-terms and current divergences. PCAC is used for the n-and k-mesons, and two-particle unitarity is used for the l-and Of channels. The results depend on the Kappa-meson mass. Results are presented for the slope of the divergence form factor h, , the ratio I = F-(0)/F+(O),

and the width of the Kappa meson, for mK = 900 and 1100 MeV. It is found that the K has a large width,
