QCD effects to Bjorken unpolarized sum rule for vN deep-inelastic scattering

The possibility of the first measurement of Bjorken unpolarized sum rule for F-1 structure function of vN deep-inelastic scattering at neutrino factories is commented. The brief summary of various theoretical contributions to this sum rule is given. Using the next-to-leading set of parton distributions functions, we simulate the expected Q(2)-behaviour and emphasize that its measurement can allow us to determine the value of the QCD strong coupling constant alpha(s) with reasonable theoretical uncertainty, dominated by the ambiguity in the existing estimates of the twist-4 non-perturbative 1/Q(2)-effect.
