Exploratory study of high-energy neutrino interactions

We report the results of an initial investigation of high-energy neutrino interactions using a dichromatic neutrino beam. Two bands of neutrinos, from pion decay ($〈E_{\nu }〉\approx 50$ GeV) and kaon decay ($〈E_{\nu }〉\approx 145$ GeV), were incident on a counter-spark-chamber detector. We discuss analysis of events of the type ${\nu }_{\mu }+N\to {\mu }^{-}+hadrons$. Qualitative comparisons are made with lower-energy neutrino results and the deep-inelastic e-N scaling structure functions.
