A precise measurement of the muon neutrino–nucleon inclusive charged current cross section off an isoscalar target in the energy range $2.5<E_{\nu }<40\text{GeV}$ by NOMAD

Abstract

We present a measurement of the muon neutrino–nucleon inclusive charged current cross section, off an isoscalar target, in the neutrino energy range $2.5⩽E_{\nu }⩽40\text{GeV}$. The significance of this measurement is its precision, ±4% in $2.5⩽E_{\nu }⩽10\text{GeV}$, and ±2.6% in $10⩽E_{\nu }⩽40\text{GeV}$ regions, where significant uncertainties in previous experiments still exist, and its importance to the current and proposed long baseline neutrino oscillation experiments.
