Measurement of the vector form factor in the decay $K_{L} \rightarrow \pi e\nu$

The Dalitz plot of 0.5*10/sup 6/ K/sub e3/ decays has been studied to measure the q/sup 2/ dependence of the vector form factor, and to determine the effect of radiative corrections. The observed linear slope of the form factor lambda /sub +/=0.0312+or-0.0025 is compatible with the prediction of K*...

description The Dalitz plot of 0.5*10/sup 6/ K/sub e3/ decays has been studied to measure the q/sup 2/ dependence of the vector form factor, and to determine the effect of radiative corrections. The observed linear slope of the form factor lambda /sub +/=0.0312+or-0.0025 is compatible with the prediction of K* dominance. Deviations of the electron spectra from those of a pure vector transition are measured and found in agreement with expected radiative corrections. (11 refs).
