Testing QCD predictions beyond the leading order for non-singlet structure functions in neutrino scattering

Quantum chromodynamics predictions for the non-singlet pieces of the structure functions in neutrino inlcusive scattering are tested against experiment. Next-to-leading QCD terms, and higher-twist contributions are taken into account. After discussing the uncertainties (both experimental and theoretical) inherent to the untempered use of moments, pointwise reconstruction is effected. The ensuing fits to experimental data are exellent in all the x, Q2 region explored (2 GeV2 <= Q2 <= 180 GeV2). The preferred value of Δ (defined in the minimal renormalization scheme) obtained is Δ = 0.17 +- 0.08 GeV, perfectly compatible with one found previously from ep, μp scattering Δ = 0.20 +- 0.06.
