We present the results of non-singlet QCD analysis of xF3(x,Q2) structure function in NLO and NNLO which are performed based on charged current (CC) neutrino-nucleon deep inelastic scattering (DIS). In this analysis we extract the valence quark parton distributions xuv(x,Q2) and xdv(x,Q2) in a wide range of x and Q2, and determine their parameterization in two different scenarios with the correlated errors using xFitter package. We determine the strong coupling of Undefined control sequence alphs up to NNLO and perform a comparison with other determinations of Undefined control sequence alphs in deeply inelastic scattering. Our results for valence quark distributions and the strong coupling constant at NLO and NNLO are compatible with the available theoretical models.
