“…The statistical and systematic uncertainties, which are dominated by the flux, are still too large for a measurement of this component. Future foreseen reduction of such uncertainties, with more ND280 data and relying on NA61/SHINE T2K replica target data for flux tuning [86], will improve the sensitivity to the axial-vector 2p2h component. In some bins the difference is negative since antineutrinos can interact with the hydrogen of the hydrocarbon molecule, leading to a cross section for antineutrino higher than for neutrino.…”

This paper presents the first combined measurement of the double-differential muon neutrino and antineutrino charged-current cross sections with no pions in the final state on hydrocarbon at the off-axis near detector of the T2K experiment. The data analyzed in this work comprise 5.8 × 10 20 and 6.3 × 10 20 protons on target in neutrino and antineutrino mode respectively, at a beam energy peak of 0.6 GeV. Using the two measured cross sections, the sum, difference, and asymmetry were calculated with the aim of better understanding the nuclear effects involved in such interactions. The extracted measurements have been compared with the prediction from different Monte Carlo generators and theoretical models showing that the difference between the two cross sections have interesting sensitivity to nuclear effects.

“…Uncertainties in the hadronic interaction cross section are the dominant contribution to the assigned 6%-8% flux uncertainties. This represents a large improvement over previous T2K analyses, due to improved hadron production and interaction constraints from NA61/SHINE measurements using a replica of the T2K target [38].…”

“…The neutrino flux is estii th mated by simulation based on FLUKA2011 [32] and GEANT3 [33] for modeling hadronic interactions and particle transport and decays in the beamline. Pion and kaon production cross sections are renormalized using data from the NA61/SHINE experiment taken using both thin and T2K replica targets [34][35][36][37][38]. Oscillations are taken into account for neutrinos that produce charged-current (CC) interactions at SK, using parameters from the recent T2K measurements [23].…”

Neutrino-and antineutrino-oxygen neutral-current quasielasticlike interactions are measured at Super-Kamiokande using nuclear deexcitation γ rays to identify signal-like interactions in data from a 14.94ð16.35Þ × 10 20 protons-on-target exposure of the T2K neutrino (antineutrino) beam. The measured flux-averaged cross sections on oxygen nuclei are hσ ν-NCQE i ¼ 1.70 AE 0.17ðstat:Þ þ0.51 −0.38 ðsyst:Þ × 10 −38 cm 2 =oxygen with a fluxaveraged energy of 0.82 GeV and hσ¯ν -NCQE i ¼ 0.98 AE 0.16ðstat:Þ þ0.26 −0.19 ðsyst:Þ × 10 −38 cm 2 =oxygen with a flux-averaged energy of 0.68 GeV, for neutrinos and antineutrinos, respectively. These results are the most precise to date, and the antineutrino result is the first cross section measurement of this channel. They are compared with various theoretical predictions. The impact on evaluation of backgrounds to searches for supernova relic neutrinos at present and future water Cherenkov detectors is also discussed.

“…Although these data are very valuable, they are insufficient for the precise neutrino flux predictions due to low precision and lack of error covariances. In more recent years, experiments like NA61/SHINE [4][5][6][7], HARP [8,9] or MIPP [10][11][12] took valuable data with the direct requests and input from the neutrino experiments. These data include cross-section and hadron production measurement for various targets and beam momenta.…”

The next generation of long-baseline neutrino experiments will be capable of precision measurements of neutrino oscillation parameters, precision neutrino-nucleus scattering, and unprecedented sensitivity to physics beyond the Standard Model. Reduced uncertainties in neutrino fluxes are necessary to achieve high precision and sensitivity in these future precise neutrino measurements. New measurements of hadron-nucleus interaction cross sections are needed to reduce uncertainties of neutrino fluxes. We report measurements of the differential cross section as a function of scattering angle for proton-carbon interactions with a single charged particle in the final state at beam momenta of 20, 30, and 120 GeV/c. These measurements are the result of a beam test for EMPHATIC, a hadron-scattering and hadron-production experiment. The total, elastic and inelastic cross-sections are also extracted from the data and compared to previous measurements. These results can be used in current and future long-baseline neutrino experiments, and demonstrate the feasibility of future measurements by an upgraded EMPHATIC spectrometer.
