Influence of Nonperturbative Effects on the Scaling Violation in Neutrino Interactions at Q sup 2 =2-100 GeV sup 2

摘要

Combined analysis of nonperturbative and perturbative contributions to the scaling violation of nucleon structure functions, measured in neutrino interactions at Q/sup 2/=2-100 GeV/sup 2/, has been fulfilled. The value of the QCD parameter lambda /sub M-tilder S/ has been found to be 0.50+-0.11 (stat.) GeV. Nonperturbative contribution has a negative sign and its x-dependence is described by x/sup 2//(1-x) form quite well. 11 refs.; 2 figs. (Atomindex citation 19:070852)
