Description
The axial form factors for the Kl4 decay are calculated using models with hidden local symmetry to describe JP=1- resonances. The relation between this approach and low-energy expansion is clarified. It is shown that the explicit breaking of chiral symmetry has no significant effect on the predictions. It turns out that in order to achieve a satisfying description an additional S-wave contribution is needed, which can be described by a JP=0+ resonance
