A subtracted dispersive representation of the Kπ vector form factor, F Kπ + , is used to fit the Belle spectrum of τ → Kπν τ decays incorporating constraints from results on K l3 decays. Through the use of three subtractions, the slope and curvature of F Kπ + are obtained directly from the data yiel

Some time ago a dispersive representation of the scalar Kπ form factor has been proposed. It does not only allow to limit the number of free parameters in the analysis of the experimental K l3 decay data on physically motivated ground, but the main interest is that it allows via the Callan-Treiman l
