Measurement of the muon neutrino charged-current cross sections on water, hydrocarbon and iron, and their ratios, with the T2K on-axis detectors


Journal Article

© 2019 The Author(s). We report a measurement of the flux-integrated νμ charged-current cross sections on water, hydrocarbon, and iron in the T2K on-axis neutrino beam with a mean neutrino energy of 1.5 GeV. The measured cross sections on water, hydrocarbon, and iron are σH2oCC = (0.840±0.010(stat.)+0.10-0.08(syst.)) ×10-38 cm2/nucleon, σCHCC = (0.817±0.007(stat.)+0.11-0.08(syst.)) × 10-38 cm2/nucleon, and σFeCC = (0.859±0.003(stat.)^+0.12-0.10(syst.)) ×10-38 cm2/nucleon, respectively, for a restricted phase space of induced muons: θμ < 45° and pμ > 0.4 GeV/c in the laboratory frame. The measured cross section ratios are σH2oCC/σCHCC = 1.028±0.016(stat.)±0.053(syst.), σFeCC/σH2oCC = 1.023±0.012(stat.)±0.058(syst.), and σFeCC/σCHCC = 1.049±0.010(stat.)±0.043(syst.). These results, with an unprecedented precision for the measurements of neutrino cross sections on water in the studied energy region, show good agreement with the current neutrino interaction models used in the T2K oscillation analyses.
