| Abstract: | In a study of charged KL0 three-body decays a sample of 6668 KL0 → π±e?ν candidates has been obtained. The Dalitz plot distribution is in agreement with V ? A theory, and limits are presented for scalar and tensot contributions to the weak current. Using a conventional expansion for the form factor f+ we find λ+ = 0.055 ± 0.010 with systematic effects estimated at ± 0.01. |
