Exploratory Study of High-Energy Neutrino Interactions

Abstract

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 ($〈{E}_{\ensuremath{\nu}}〉\ensuremath{\approx}50$ GeV) and kaon decay ($〈{E}_{\ensuremath{\nu}}〉\ensuremath{\approx}145$ GeV), were incident on a counter-spark-chamber detector. We discuss analysis of events of the type ${\ensuremath{\nu}}_{\ensuremath{\mu}}+N\ensuremath{\rightarrow}{\ensuremath{\mu}}^{\ensuremath{-}}+\mathrm{hadrons}$. Qualitative comparisons are made with lower-energy neutrino results and the deep-inelastic $e\ensuremath{-}N$ scaling structure functions.
