Kπ vector form factor constrained by τ → Kπντ and Kl3 decays

Dispersive representations of the K π vector and scalar form factors are used to fit the spectrum of τ → K πν τ obtained by the Belle collaboration incorporating constraints from results for K l 3 decays. The slope and curvature of the vector form factor are obtained directly from the data through t...
