Measurement of K+→π0π0e+ν (K00e4) decay using stopped positive kaons
Abstract
The K+→π0π0e+ν (K00e4) decay has been measured with stopped positive kaons for a data sample of 216 events. A comparison of the observed spectra with a Monte Carlo simulation determined the K00e4 form factor. The results are compatible with the K+→π+π-e+ν data, as estimated from the ΔI=1/2 rule. We also established that the K00e4 channel can be used to determine the π-π scattering lengths.
