✦ Synopsis

The results of the more detailed NNLO QCD analysis of the CCFR data for xFs SF are presented. The factorization scale uncertainties are analyzed. The NNLO results for as(Mz) and twist-4 contributions are obtained. Despite the fact that the amplitude of the x-shape of the twist-4 factor is consequently decreasing at the NLO and NNLO, our new QCD analysis seems to reveal the remaining twist-4 structure at the NNLO level. The definite NaLO uncertainties are fixed using the [0/2] Padd resummation technique.

We continue the systematic next-to-next-to-leading order (NNLO) QCD analysis of the CCFR data for the xF3 SF. The NNLO results for the Qe-dependence of the parameters, which describe the x-dependence of this SF, are presented.
