Measurement of inclusive double-differential νμ charged-current cross section with improved acceptance

We report a measurement of the flux-integrated cross section for inclusive muon neutrino charged-current interactions on carbon. The double differential measurements are given as function of the muon momentum and angle. Relative to our previous publication on this topic, these results have an increased angular acceptance and higher statistics. The data sample presented here is 5.7 × 10^20 protons-on-target. The total flux-integrated cross section is measured to be (6.950 ± 0.662) × 10^−39 cm^2/nucleon and is consistent with our simulation.
