It receives contributions both from the scalar resonance + ​$K_0^*(1430)$ and from the scalar projection of off-shell vector resonances. + We construct a model for the hadronic current which includes the vector + ​resonances $K^*(892)$ and $K^*(1410)$ and the scalar resonance + ​$K_0^*(1430)$. The parameters of the model are fixed + by matching to the $O(p^4)$ predictions of chiral perturbation theory. + ​Suitable angular correlations of the $K\pi$ system + allow for a model independent separation of the vector and scalar + form factor. ​ Numerical results for the relevant + ​structure functions are presented. + ​ + |**Markus Finkemeier and Erwin Mirkes** ​ | + |** Z.
