Abstract
Neutral-kaon decays to pi e nu were analysed to determine the q(2) dependen ce of the K-e3(0), electroweak form factor f(+). Based on 365612 events, th is form factor was found to have a linear dependence on q(2) with a slope l ambda(+) = 0.0245 +/- 0.0012(stat) +/- 0.0022(syst). (C) 2000 Published by Elsevier Science B.V.
