The interplay between perturbative QCD and power corrections: the description of scaling or automodelling limit violation in deep-inelastic scattering

Abstract

The summary of the results of our next-to-next-to-leading fits of Tevatron experimental data for $x{F}_3$ structure function of the $\nu N$ deep-inelastic scattering is given. The special attention is paid to the extraction of twist-4 contributions and demonstration of the interplay between these effects and higher-order perturbative QCD corrections. The factorization and renormalization scale uncertainties of the results obtained are analysed
