Abstract

The new theoretical input to the analysis of the experimental data of the CCFR collaboration for F₃ structure function of νN deep inelastic scattering is considered. This input comes from the next-to-next-to-leading order corrections to the anomalous dimensions of the Mellin moments of the F₃ structure function. The QCD scale Λ_MS⁽⁴⁾ is extracted from higher-twist independent fits. The results obtained demonstrate the minimization of the influence of perturbative QCD contributions to the value of Λ_MS⁽⁴⁾
