Measurement of the Form Factors in the Decay KoL → πμν
Abstract
A Dalitz plot of 1.6 x 106 KoL → πμν decays has been studied to measure the t dependence of the vector and scalar form factors. Here, the observed slopes, λ+ = 0.030 ± 0.003 and λ0 = 0.020 ± 0.003, are compatible with current algebra and soft pion predictions, μ - e universality, and K* (890) dominance of the vector form factor.
