QCD analysis of non-singlet structure function xF3 in deep inelastic neutrino-nucleon scattering

In this paper we intend to determine valence quarks distribution functions u ,d in a wide ‎range of x and Q‏2‏‎, with using experimental data groups such as CCFR, NuTeV, CHORUS ‎and CDHSW , and‏ ‏determine their correlated errors using xFitter framework. We ‎extracted‎ the results for valence quarks distribution functions‎‏ ‏with their uncertainties‎ and ‎compared them with other models. Our results are in agreement with the results of other ‎various models and recent PDG results for strong coupling‏ ‏constant in two approximations ‎NLO and NNLO. The extracted results for valence-quark distributions are in good ‎agreement with available theoretical models.‎
