Chiral Symmetry Breaking inKl3Decays

A current-algebra calculation of the $K_{l3\mathrm{}}$ form factors is made under the assumption that the chiral SU(3) symmetry is broken by an interaction which transforms under the representation (3, 3*) ⊕ (3*, 3). Quantitative results on the weak decay parameters of the mesons, the $\kappa$ meson mass, and the form factor $f_{+}\mathrm{}\left(0\right)\mathrm{}$ are obtained. The factor $\xi$ is found to be very nearly zero.
