“…The systematic uncertainty on the observed rate in the MINERvA medium (low) energy measurement was 1.8% (5%), and was mostly due to uncertainties in the background reactions. The uncertainty on background reactions, particularly the low Q 2 behavior of the ν e quasielastic-like background events, is significantly lower in the medium energy analysis than in the low energy analysis, largely due to better knowledge of the low Q 2 behavior of neutrino reactions due to MINERvA data itself [15,16]. In the medium energy analysis, the electron reconstruction efficiency and electromagnetic energy scale of the detector were also noted contributors of systematic uncertainty, but were not dominant sources.…”

“…MINERvA have observed a deviation between Monte Carlo expectation and data as a function of reconstructed Q 2 (see Ref. [16] for a definition) for ν µ -CH andν µ -CH charged current quasielastic-like events. In particular, there is a strong suppression at low Q 2 values, which might correspond to the region of overlap between the signal and background templates.…”

“…In particular, there is a strong suppression at low Q 2 values, which might correspond to the region of overlap between the signal and background templates. MINERvA has concluded, however, that the majority of this disagreement is due not to truly quasielastic events which would create background to a neutrino-electron scattering analysis, but rather to higher recoil processes such as pion production where the pion is observed in nuclear final state interactions [15,16]. In order to investigate this effect on the analysis, the input ν e -40 Ar andν e -40 Ar background events are modified from the nominal GENIE prediction by reweighting according to the observed MINERvA ratio, as a function of true Q 2 .…”

Neutrino-electron elastic scattering for flux determination at the DUNE oscillation experiment

We study the feasibility of using neutrino-electron elastic scattering to measure the neutrino flux in the DUNE neutrino oscillation experiment. The neutrino-electron scattering cross section is precisely known, and the kinematics of the reaction allow determination of the incoming neutrino energy by precise measurement of the energy and angle of the recoiling electron. For several possible near detectors, we perform an analysis of their ability to measure neutrino flux in the presence of backgrounds and uncertainties. With realistic assumptions about detector masses, we find that a liquid argon detector, even with limitations due to angular resolution, is able to perform better than less dense detectors with more precise event-by-event neutrino energy measurements. We find that the absolute flux normalization uncertainty can be reduced from ∼8% to ∼2%, and the uncertainty on the flux shape can be reduced by ∼20-30%.

“…Recent developments in neutrino phenomenology motivate certain augmentations to GENIE that are implemented via event reweighting and by adding a simulated sample of quasielastic-like 2-particle 2-hole (2p2h) events [44]. The refinements (described below) are very similar to those used in the reference simulations of recent, published MINERvA measurements [8,13,42,[45][46][47][48][49]. Importantly, all refinements to the GENIE-based MC used here (version designation MnvGENIE v1.2) were decided prior to the present work, and the data analyzed here were not used in the GENIE tuning.…”

The antineutrino scattering channelνµ CH → µ + π − X(nucleon(s)) is analyzed in the incident energy range 1.5 to 10 GeV using the MINERvA detector at Fermilab. Differential cross sections are reported as functions of µ + momentum and production angle, π − kinetic energy and production angle, and antineutrino energy and squared four-momentum transfer. Distribution shapes are generally reproduced by simulations based on the GENIE, NuWro, and GiBUU event generators, however GENIE (GiBUU) overestimates (underestimates) the cross-section normalizations by 8% (10%). Comparisons of data with the GENIE-based reference simulation probe conventional treatments of cross sections and pion intranuclear rescattering. The distribution of non-track vertex energy is used to decompose the signal sample into reaction categories, and cross sections are determined for the exclusive reactions µ + π − n and µ + π − p. A similar treatment applied to the published MINERvA sampleνµ CH → µ + π 0 X(nucleon(s)) has determined the µ + π 0 n cross section, and the latter is used with σ(π − n) and σ(π − p) to carry out an isospin decomposition ofνµ-induced CC(π). The ratio of magnitudes and relative phase for isospin amplitudes A3 and A1 thereby obtained are: Rν = 0.99 ± 0.19 and φν = 93 • ± 7 • . Our results are in agreement with bubble chamber measurements made four decades ago.

Elastic neutrino scattering on electrons is a precisely-known purely leptonic process that provides a standard candle for measuring neutrino flux in conventional neutrino beams. Using a total sample of 810 neutino-electron scatters after background subtraction, the measurement reduces the normalization uncertainty on the νµ NuMI flux between 2 and 20 GeV from 7.5% to 3.9%. This is the most precise measurement of neutrino-electron scattering to date, will reduce uncertainties on MINERνA's absolute cross section measurements, and demonstrates a technique that can be used in future neutrino beams such as LBNF.PACS numbers: definitely not 99.99+z
