Abstract :
The QCD analysis of the xF3 structure function measured in deep-inelastic scattering of neutrinos and antineutrinos on an iron target at the Fermilab Tevatron is done in 1-, 2- and 3-loop order of QCD. The x dependence of the higher-twist contribution is evaluated. The experimental value of higher-twist corrections to the Gross-Llewellyn Smith sum rule is discussed.
