摘要：Recently, we introduced several dispersive representations for the vector Kp form factor and fitted them to the Belle spectrum of t ! Kpnt . 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 t !Kpnt and Ke3 spectra.
