Next-to-next-to-leading order fits to CCFR'97 xF3 data and infrared renormalons
Abstract
We briefly summarize the outcome of our recent improved fits to the experimental data of CCFR collaboration for xF3 structure function of nuN deep-inelastic scattering at the next-to-next-to-leading order. Special attention is paid to the extraction of alphas(MZ) and the parameter of the infrared renormalon model for 1/Q2-correction at different orders of the perturbation theory. The results can be of interest for planning similar studies using possible future data of Neutrino Factories.
