K pi vector form factor from a dispersive representation and fits to tau decay data
2009
Proceedings of International Workshop on Effective Field Theories: from the pion to the upsilon — PoS(EFT09)
unpublished
Recently, we introduced several dispersive representations for the vector Kπ form factor and fitted them to the Belle spectrum of τ → Kπν τ . Here, we briefly present the model and discuss the results for the slope and curvature of F + (s) arising from the best fit. Furthermore, we compare the pole position of the charged K * (892) computed from our model with other results in the literature. Finally, we discuss the prospects of a simultaneous fit to τ → Kπν τ and K e3 spectra. International
