Resumen
Using the published KTeV samples of KL→π±e "ν and KL→π±μ "ν decays, we perform a reanalysis of the scalar and vector form factors based on the dispersive parametrization. We obtain phase-space integrals IKe=0.15446±0.00025 and IKμ=0.10219±0.00025. For the scalar form factor parametrization, the only free parameter is the normalized form factor value at the Callan-Treiman point (C); our best-fit results in lnC=0.1915±0.0122. We also study the sensitivity of C to different parametrizations of the vector form factor. The results for the phase-space integrals and C are then used to make tests of the standard model. Finally, we compare our results with lattice QCD calculations of FK/Fπ and f+(0). © 2010 The American Physical Society. 81 5
