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 GeV by NOMAD

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 Eν 40 GeV. The significance of this measurement is its precision, ±4% in 2.5 Eν 10 GeV, and ±2.6% in 10 Eν 40 GeV regions, where significant uncertainties in previous experiments still exist, and its importance to the current and proposed long baseline neutrino oscillation experiments.
