Influence of nonperturbative effects on the violation of scaling in neutrino interactions at O2=2.0-100.0 GeV2
The contributions of perturbative and nonperturbative effects to the violation of scaling are analyzed jointly for the structure functions of the nucleon measured in neutrino interactions at 2.0 < Q 2 < 100.0 GeV2. The value Лш = 0.50 ± 0.11 GeV is found for the constant of quantum chromodynamics (the error is statistical). The contribution of the nonperturbative effects is negative, and its л: dependence is described well by x2/( 1-х).
