Application of New Multiloop QCD Input to the Analysis of xF3 Data

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 and N³LO corrections to the related coefficient funtions. The QCD scale parameter Λ {{(4)} / {MS}} 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 {{(4)} / {MS}} .
