Abstract

The form factors of the decay K⁺ → π⁺e⁺ν_e (K_e3) have been determined from the comparison of the experimental and Monte Carlo Dalitz distributions containing about 10⁵ K_e3 events. The following values of the parameters were obtained: λ₊ = 0.0278 ± 0.0017 (stat.) ± 0.0015 (syst.), |f_S/f₊(0)| = 0.0040 ± 0.0160 (stat.) ± 0.0067 (syst.), and |f_T/f₊(0)| = 0.019 ± 0.080 (stat.), ± 0.038 (syst.). Both scalar f_S and tensor f_T form factors are consistent with the Standard Model predictions of zero values.
