A Precise Measurement of the Muon Neutrino–nucleon Inclusive Charged Current Cross Section off an Isoscalar Target in the Energy Range 2.5<eν<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⩽40GeV. The significance of this measurement is its precision, ±4% in 2.5⩽Eν⩽10GeV, and ±2.6% in 10⩽Eν⩽40GeV regions, where significant uncertainties in previous experiments still exist, and its importance to the current and proposed long baseline neutrino oscillation experiments.
