“…The primary protons at the NuMI beamline are sent from the main injector, and meson productions from other than the primary proton-target interactions are high. The full NuMI target measurement is done at the MIPP experiment [162] at Fermilab, but this result is not yet fully implemented in the NuMI neutrino flux simulation. Thus, there is a chance that NuMI absolute flux normalization could be shifted in the future.…”

Abstract. Neutrino oscillations physics is entered in the precision era. In this context accelerator-based neutrino experiments need a reduction of systematic errors to the level of a few percent. Today one of the most important sources of systematic errors are neutrinonucleus cross sections which in the hundreds-MeV to few-GeV energy region are known with a precision not exceeding 20%. In this article we review the present experimental and theoretical knowledge of the neutrino-nucleus interaction physics. After introducing neutrino oscillation physics and accelerator-based neutrino experiments, we overview general aspects of the neutrino-nucleus cross sections, both theoretical and experimental views. Then, we focus on these quantities in different reaction channels. We start with the quasielastic and quasielastic-like cross section, putting a special emphasis on multinucleon emission channel which attracted a lot of attention in the last few years. We review the main aspects of the different microscopic models for this channel by discussing analogies and differences among them. The discussion is always driven by a comparison with the experimental data. We then consider the one pion production channel where data-theory agreement remains very unsatisfactory. We describe how to interpret pion data, then we analyze in particular the puzzle related to the impossibility of theoretical models and Monte Carlo to simultaneously describe MiniBooNE and MINERvA experimental results. Inclusive cross sections are also discussed, as well as the comparison between the ν µ and ν e cross sections, relevant for the CP violation experiments. The impact of the nuclear effects on the reconstruction of neutrino energy and on the determination of the neutrino oscillation parameters is reviewed. A window to the future is finally opened by discussing projects and efforts in future detectors, beams, and analysis.

“…The flux of neutrinos delivered to the detectors is calculated using a simulation of the production and transport of particles through the beamline components [22,25] reweighted to incorporate external measurements [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45]. Neutrino interactions in the detector are simulated using GENIE [46] tuned to improve agreement with external measurements and ND data, reducing uncertainties in the extrapolation of measurements in the ND to the FD.…”

The NOvA experiment has seen a 4.4σ signal ofν e appearance in a 2 GeVν μ beam at a distance of 810 km. Using 12.33 × 10 20 protons on target delivered to the Fermilab NuMI neutrino beamline, the experiment recorded 27ν μ →ν e candidates with a background of 10.3 and 102ν μ →ν μ candidates. This new antineutrino data are combined with neutrino data to measure the parameters jΔm 2 32 j ¼ 2.48 þ0.11 −0.06 × 10 −3 eV 2 =c 4 and sin 2 θ 23 in the ranges from (0.53-0.60) and (0.45-0.48) in the normal neutrino mass hierarchy. The data exclude most values near δ CP ¼ π=2 for the inverted mass hierarchy by more than 3σ and favor the normal neutrino mass hierarchy by 1.9σ and θ 23 values in the upper octant by 1.6σ.

“…NOvA uses a comprehensive flux prediction package that uses all available and relevant hadron production data (discussed in Section 4.1.1). It uses data from the pion and kaon yields measured by the MIPP [128] and from NA49 [21] experiments. The uncertainty in the flux prediction when integrated from 0-20 GeV is 7.8%, with hadron production uncertainties still dominating [18].…”

“…All these events are shown within the 10 µs spill window. Historically, there have been measurements of the charged pion production yields off the NuMI target [128] and flux predictions using all available data from hadron production [18], but the yield of kaon production has not been well measured [94].…”
