Dispersive representation of the K pi vector form factor and fits to tau -> K pi nu(tau) and Ke3 data
Recently, we introduced several dispersive representations for the vector Kπ form factor and fitted them to the Belle spectrum of τ→Kπντ. 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 positi...

| Sumario: | Recently, we introduced several dispersive representations for the vector Kπ form factor and fitted them to the Belle spectrum of τ→Kπντ. 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→Kπντ and Ke3 spectra. |
