Measurement of the charged-current cross sections on water, hydrocarbon, iron, and their ratios with the T2K on-axis detectors
We report a measurement of the flux-integrated 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 = (0.840(stat.)(syst.))10cm/nucleon, = (0.817(stat.)(syst.))10cm/nucleon, and = (0.859(stat.) (syst.))10cm/nucleon respectively, for a restricted phase space of induced muons: and 0.4 GeV/ in the laboratory frame. The measured cross section ratios are = 1.028(stat.)(syst.), = 1.023(stat.)(syst.), and = 1.049(stat.)(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
Measurement of the charged-current electron (anti-)neutrino inclusive cross-sections at the T2K off-axis near detector ND280
The electron (anti-)neutrino component of the T2K neutrino beam constitutes the largest background in the measurement of electron (anti-)neutrino appearance at the far detector. The electron neutrino scattering is measured directly with the T2K off-axis near detector, ND280. The selection of the electron (anti-)neutrino events in the plastic scintillator target from both neutrino and anti-neutrino mode beams is discussed in this paper. The flux integrated single differential charged-current inclusive electron (anti-)neutrino cross-sections, dσ/dp and dσ/d cos(θ), and the total cross-sections in a limited phase-space in momentum and scattering angle (p > 300 MeV/c and θ ≤ 45°) are measured using a binned maximum likelihood fit and compared to the neutrino Monte Carlo generator predictions, resulting in good agreement
