“…More recently, this same data has been re-analyzed using modern vector form factors as input. The use of improved non-dipole vector form factors (10) slightly shifts the best-fit axial mass values obtained from this data; however the conclusion is still that MA≈1.0 GeV (11,12). These results are consistent with those obtained from the electro-production of pions produced near threshold (9).…”

The study of neutrino oscillations has necessitated a new generation of neutrino experiments that are exploring neutrino-nuclear scattering processes. We focus in particular on charged-current quasi-elastic scattering, a particularly important channel that has been extensively investigated both in the bubble-chamber era and by current experiments. Recent results have led to theoretical reexamination of this process. We review the standard picture of quasi-elastic scattering as developed in electron scattering, review and discuss experimental results, and discuss additional nuclear effects such as exchange currents and short-range correlations that may play a significant role in neutrino-nucleus scattering.

“…The generalization proposed in [52,53] takes into account the final lepton mass and is based upon a covariant form of the charged leptonic current with definite lepton helicity. In our MC simulation we use the same set of 18 interfering nucleon resonances with masses below 2 GeV as in [50] but with all relevant input parameters updated according to the current data [49,54].…”

We have studied the muon neutrino and antineutrino quasi-elastic (QEL) scattering reactions (ν μ n → μ − p andν μ p → μ + n) using a set of experimental data collected by the NOMAD Collaboration. We have performed measurements of the cross-section of these processes on a nuclear target (mainly carbon) normalizing it to the total ν μ (ν μ ) charged-current cross section. The results for the flux-averaged QEL cross sections in the (anti)neutrino energy interval 3-100 GeV are σ qel ν μ = (0.92 ± 0.02(stat) ± 0.06(syst)) × 10 −38 cm 2 and σ qel ν μ = (0.81 ± 0.05(stat) ± 0.09(syst)) × 10 −38 cm 2 for neutrino and antineutrino, respectively. The axial mass parameter M A was extracted from the measured quasi-elastic neutrino cross section. The corresponding result is M A = 1.05±0.02(stat)±0.06(syst) GeV. It is consistent with the axial mass values recalculated from the antineutrino cross section and extracted from the pure Q 2 shape analysis of the high purity sample of ν μ quasielastic 2-track events, but has smaller systematic error and should be quoted as the main result of this work. Our measured M A is found to be in good agreement with the world average value obtained in previous deuterium filled bubble chamber experiments. The NOMAD measurement of M A is lower than those recently published by K2K and MiniBooNE Collaborations. However, within the large errors quoted by these experiments on M A , these results are compatible with the more precise NOMAD value.PACS 13.15.+g · 25.30.Pt

“…The value of the axial mass parameter M RES A = 1.12 GeV has been derived in Ref. [10] by fitting to the data available at that time. All known nucleon resonances with masses below ≈ 2 GeV are included and the interference of their amplitudes is properly taken into account according to Ref.…”

“…This point will be discussed at length in a forthcoming paper. Here we only mention the effect of finite lepton mass to the leptonic currents [6], including the pion-pole contribution into the weak hadronic current [9], the effect of interference between the 08003-p. 2 Very Large Volume Neutrino Telescope (VLVnT-2015) Dashed, dash-dotted and thin solid lines correspond to contributions from QES, RES and DIS, respectively. Shaded bands show the uncertainties.…”

Abstract. An updated set of (anti)neutrino-nucleon charged and neutral current cross sections at 3 GeV E ν 100 GeV is presented. These cross sections are of particular interest for the detector optimization and data processing and interpretation in the future Megaton-scale experiments like PINGU, ORCA, and Hyper-Kamiokande. Finite masses of charged leptons and target mass corrections in exclusive and deep inelastic (ν)νN interactions are taken into account. A new set of QCD NNLO parton density functions, ABMP15, is used for calculation of the DIS cross sections. The sensitivity of the cross sections to phenomenological parameters and to extrapolations of the nucleon structure functions to small x and Q 2 is studied. An agreement within the uncertainties of our calculations with experimental data is demonstrated.
