 +====== TTP95-44 The Scalar Contribution to $\tau\to K\pi\nu_\tau$ ====== 
 +   <​hidden TTP95-44 ​ The Scalar Contribution to $\tau\to K\pi\nu_\tau$ > We consider the scalar form factor in $\tau \to K\pi \nu_\tau$ 
 + ​decays. 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.
