“…The HCAL surrounds the ECAL; it consists of alternating layers of scintillator and 2.54 cm thick steel plates. The readout electronics have a timing resolution of 3.0 ns for hits of mini-mum ionizing particles [34], enabling efficient separation of multiple interactions within a single 10 µs beam spill.…”

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.

“…The most stringent limits on p → K + ν come from SK, where the largest background is from neutral-current K + by atmospheric neutrinos where no final-state particles are above Cherenkov threshold [22]. Recently, differential cross sections for CC and NC K + production have been measured by MINERvA [117,118].…”

Neutrino interactions with nuclei have been the subject of intense interest over the last 15 years.Current and future measurements of neutrino oscillation and exotic physics use order 0.1-10 GeV neutrinos on a range of nuclear targets ( 12 C, 16 O, 40 Ar). As the precision of these experiments has increased, information from their detectors and dedicated experiments indicate deficiencies in the modeling of neutrino interactions on nuclear targets. Here, we present the current state of knowledge about neutrino-nucleus interactions, the challenge of extracting the cross section of these processes, and current experimental puzzles in the field. We also look forward to new and novel measurements and efforts in the future which seek to resolve these questions.

“…Events with rear-exiting tracks are excluded from the sideband in order to make the composition of the backgrounds in the signal and sideband regions more similar, as well as to exclude events at low inelasticity y = (E ν − E µ )/E ν , since CC backgrounds in the signal region are at high y. Backgrounds due to beam pileup are constrained by the method described in Ref. [50]. All other backgrounds are constrained together using the CC-rich sideband, and a scale factor of 0.96 ± 0.23 is The highest bin includes all events above 850g/cm 2 and is not normalized by the bin width, and the lowest bin includes events in which the K + is the only reconstructed track.…”

Neutral-current production of K + by atmospheric neutrinos is a background in searches for the proton decay p → K + ν. Reactions such as νp → νK + Λ are indistinguishable from proton decays when the decay products of the Λ are below detection threshold. Events with K + are identified in MINERvA by reconstructing the timing signature of a K + decay at rest. A sample of 201 neutrinoinduced neutral-current K + events is used to measure differential cross sections with respect to the K + kinetic energy, and the non-K + hadronic visible energy. An excess of events at low hadronic visible energy is observed relative to the prediction of the neut event generator. Good agreement is observed with the cross section prediction of the genie generator. A search for photons from π 0 decay, which would veto a neutral-current K + event in a proton decay search, is performed, and a 2σ deficit of detached photons is observed relative to the genie prediction.
