Description

The form factors of the decay K+→π0e+νe (Ke3) have been determined from the comparison of the experimental and Monte Carlo Dalitz distributions containing about 105 Ke3 events. The following values of the parameters were obtained: λ+=0.0278±0.0017 (stat.)±0.0015 (syst.), |fS/f+(0)|=0.0040±0.0160 (stat.) ±0.0067 ( syst. ), and |fT/f+(0)|=0.019±0.080 (stat.) ±0.038 (syst.). Both scalar fS and tensor fT form factors are consistent with the Standard Model predictions of zero values
