Dispersive analysis of K_{L mu3} and K_{L e3} scalar and vector form factors using KTeV data

KTeV collaboration, E. Abouzaid et al., V. Bernard +3

Using the published KTeV samples of K_L --> pi^{\pm} e^{\mp} nu and K_L --> pi^{\pm} mu^{\mp} nu decays [1], we perform a reanalysis of the scalar and vector form factors based on…
