Next-to-next-to-leading order fits to CCFR'97 $x{F}_3$ data and infrared renormalons

Abstract

We briefly summarize the outcomes of our recent improved fits to the experimental data of CCFR collaboration for $x{F}_3$ structure function of $\hat{I}½N$ deep-inelastic scattering at the next-to-next-to-leading order. Special attention is paid to the extraction of $\hat{I}{\pm }_s(M_Z)$ and the parameter of the infrared renormalon model for $1/Q^2$-correction at different orders of perturbation theory. The results can be of interest for planning similar studies using possible future data of Neutrino Factories.
