Next-to-next-to-leading order QCD analysis of the CCFR data for xF3 and F2 structure functions of the deep-inelastic neutrino-nucleon scattering

The next-to-next-to-leading order (NNLO) non-singlet QCD analysis of the experimental data of the CCFR collaboration for the xF3 and F2 structure functions of the deep-inelastis scattering of neutrinos and antineutrinos on the nucleon by means of the Jacobi polynomial expansion method is made. We demonstrate that the NNLO corrections have the important physical effects. The obtained NNLO results for αs(MZ) are: αs(MZ) = 0.109±0.003(stat)±0.005(syst)±0.003(theor) (from xF3 data) and αs(MZ) = 0.111±0.002(stat)±0.003(syst)±0.003(theor) (from the combined xF3 and F2 data). We also estimate the values of the order O(αs2)-corrections to the Gottfried sum rule.
