“…The average value is S A = 1.01 ± 0.08 ± 0.18. However, as pointed out by Sterman et al [21], the total νN cross section used by the WA25 group is smaller than the presently accepted value [91,92]. If the WA25 value is readjusted to fit this total cross section their result becomes S A = 1.08 ± 0.08 ± 0.18.…”

“…The NuTeV group measured R ν = 0.3916 ± 0.0007 and R ν = 0.4050 ± 0.0016. The quantity r = 0.499±0.005 was taken from the world average of ν − F e charged-current DIS reactions [103,104] and from measurements by the CCFR collaboration [17]. Since acceptances and cuts differ for ν and ν reactions, they did not directly construct the Paschos-Wolfenstein ratio via Eq.…”

This review article discusses the experimental and theoretical status of partonic charge symmetry. It is shown how the partonic content of various structure functions gets redefined when the assumption of charge symmetry is relaxed. We review various theoretical and phenomenological models for charge symmetry violation in parton distribution functions. We summarize the current experimental upper limits on charge symmetry violation in parton distributions. A series of experiments are presented, which might reveal partonic charge symmetry violation, or alternatively might lower the current upper limits on parton charge symmetry violation.

“…No direct measurement of the absolute flux was possible in the QTB. The absolute normalization of the ν µ flux was fixed to the constraint that the neutrino-nucleon total cross-section equaled the world average of the isoscalar-corrected Fe target experiments, σ ν F e /E ν = (0.677 ± 0.014) × 10 −38 cm 2 /GeV [9,10]. The relative flux determination, i.e.…”

“…Another major source of systematic error is the error in the value of σ ν /σ ν , the ratio of the total ν to ν cross-section. The value chosen was the world average of ν-Fe DIS experiments, including this one [10,11], σ ν /σ ν = 0.499 ± 0.007. Other sources of systematic error were investigated, including systematic errors in the flux extraction and variations in the physics model used in the Monte Carlo, but the effects of these other sources were small [11].…”

We present an improved determination of the proton structure functions F2 and xF3 from the CCFR ν-Fe deep inelastic scattering (DIS) experiment. Comparisons to high-statistics chargedlepton scattering results for F2 from the NMC, E665, SLAC, and BCDMS experiments, after correcting for quark-charge and heavy-target effects, indicate good agreement for x > 0.1 but some discrepancy at lower x. The Q 2 evolution of both the F2 and xF3 structure functions yields the quantum chromodynamics (QCD) scale parameter Λ NLO,(4) M S = 337 ± 28(exp.) M eV . This corresponds to a value of the strong coupling constant at the scale of mass of the Z-boson of αS(M 2 Z ) = 0.119 ± 0.002(exp.)±0.004(theory) and is one of the most precise measurements of this quantity.PACS numbers: 13.15.+g, 12.38. Qk, 24.85.+p, 25.30.Pt High-energy neutrinos are a unique probe for testing QCD and understanding the parton properties of nucleon structure. Combinations of neutrino and antineutrino scattering data are used to determine the F 2 and xF 3 structure functions (SFs) which determine the valence, sea, and gluon parton distributions in the nucleon [1,2]. The universalities of parton distributions can also be studied by comparing neutrino and charged-lepton scattering data. Past measurements have indicated that F ν 2 differs from F e/µ 2 by 10-20% in the low-x region. These differences are larger than the quoted experimental errors of the measurements and may indicate the need for modifications of the theoretical modeling to include higher-order or new physics contributions. QCD predicts the scaling violations (Q 2 dependence) of F 2 and xF 3 and, experimentally, the observed scaling violations can be tested against those predictions to determine α S [3] or the related QCD scale parameter, Λ QCD . The α S determination from neutrino scattering has a small theoretical uncertainty since the electroweak radiative corrections, scale uncertainties, and next-to-leading order (NLO) corrections are well understood.In this paper, we present an updated analysis of the Columbia-Chicago-Fermilab-Rochester (CCFR) collaboration neutrino scattering data with improved estimates of quark model parameters [4] and systematic uncertainties. The α S measurement from this analysis is one of the most precise due to the high energy and statistics of the experiment compared to previous measurements [5,6].
