Abstract

Faced with unresolved tensions between neutrino interaction measurements atfew-GeV neutrino energies, current experiments are forced to accept largesystematic uncertainties to cover discrepancies between their data and modelpredictions. In this paper, the widely used pion production model in GENIE iscompared to four MINERvA charged current pion production measurements usingNUISANCE. Tunings, ie, adjustments of model parameters, to help match GENIE toMINERvA and older bubble chamber data are presented here. We find thatscattering off nuclear targets as measured in MINERvA is not in good agreementwith scattering off nucleon (hydrogen or deuterium) targets in the bubblechamber data. An additional ad hoc correction for the low-$Q^2$ region, wherecollective effects are expected to be large, is also presented. While thesetunings and corrections improve the agreement of GENIE with the data, themodeling is imperfect. The development of these tunings within the NUISANCEframeworkallows for straightforward extensions to other neutrino eventgenerators and models, and allows omitting and including new data sets as theybecome available.

Abstract

Neutrino induced coherent charged pion production on nuclei,$\overline{\nu}_\mu A\to\mu^\pm\pi^\mp A$, is a rare inelastic interaction inwhich the four-momentum squared transfered to the nucleus is nearly zero,leaving it intact. We identify such events in the scintillator of MINERvA byreconstructing |t| from the final state pion and muon momenta and by removingevents with evidence of energetic nuclear recoil or production of other finalstate particles. We measure the total neutrino and antineutrino cross sectionsas a function of neutrino energy between 2 and 20 GeV and measure fluxintegrated differential cross sections as a function of $Q^2$, $E_\pi$ and$\theta_\pi$. The $Q^2$ dependence and equality of the neutrino andanti-neutrino cross-sections at finite $Q^2$ provide a confirmation of Adler'sPCAC hypothesis.

Abstract

The Spallation Neutron Source (SNS) at Oak Ridge National Laboratory is a pulsed source of neutrons and, as a by-product of this operation, an intense source of pulsed neutrinos via stopped-pion decay. The COHERENT collaboration uses this source to investigate coherent elastic neutrino-nucleus scattering and other physics with a suite of detectors. This work includes a description of our geant4 simulation of neutrino production at the SNS and the flux calculation which informs the COHERENT studies. We estimate the uncertainty of this calculation at the ∼10% level based on validation against available low-energy π+ production data.

Abstract

The antineutrino scattering channel ¯ ν μ 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 nontrack 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 sample ¯ ν μ 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 of ¯ ν μ -induced CC ( π ) . The ratio of magnitudes and relative phase for isospin amplitudes A 3 and A 1 thereby obtained are: R ¯ ν = 0.99 ± 0.19 and ϕ ¯ ν = 9 3 ° ± 7 ° . Our results are in agreement with bubble chamber measurements made four decades ago.

Abstract

MINERvA presents a new analysis of neutrino induced quasielastic-like interactions in a hydrocarbon tracking target. We report a double-differential cross section using the muon transverse and longitudinal momentum. In addition, differential cross sections as a function of the square of the four-momentum transferred and the neutrino energy are calculated using a quasielastic hypothesis. Finally, an analysis of energy deposited near the interaction vertex is presented. These results are compared to modified genie predictions as well as a NuWro prediction. All results use a data set produced by 3.34×1020 protons on target creating a neutrino beam with a peak energy of approximately 3.5 GeV.

Abstract

The total cross sections are important ingredients for the current and future neutrino oscillation experiments. We present measurements of the total charged-current neutrino and antineutrino cross sections on scintillator (CH) in the NuMI low-energy beamline using an {\em in situ} prediction of the shape of the flux as a function of neutrino energy from 2--50 GeV. This flux prediction takes advantage of the fact that neutrino and antineutrino interactions with low nuclear recoil energy ($\nu$) have a nearly constant cross section as a function of incident neutrino energy. This measurement is the lowest energy application of the low-$\nu$ flux technique, the first time it has been used in the NuMI antineutrino beam configuration, and demonstrates that the technique is applicable to future neutrino beams operating at multi-GeV energies. The cross section measurements presented are the most precise measurements to date below 5 GeV., Comment: 8 pages, 6 figures, and 12 supplemental tables of fluxes, cross sections, breakdowns of their uncertainties, and their covariance matrices
