| Abstract: | A study of prompt neutrino events from 400 GeV protons on a beam-dump is presented. The ratio of electron- to muon-neutrino rates is 0.86±0.14, in agreement withe– universality. The anti-neutrino to neutrino flux ratio is . The absolute rates and distributions observed are shown to be in quantitative agreement with the known properties of charmedquark production in hadron collisions.Supported by the Bundesministerium für Forschung und Technologic, Bonn, FRG |
