Abstract
A detailed NNLO QCD analysis of new CCFR data on thexF 3 structure function including the target mass, higher twist and nuclear corrections was performed and parametrizations of the perturbative and power terms of the structure function were constructed. The results of QCD analysis of the structure function were used to study theQ 2-dependence of the Gross—Llewellyn-Smith sum rule. The αS /π-expansion ofS GLS(Q 2) was studied and parameters of the expansion were found to bes 142.74 ± 0.01,s 2422.22 6 0.23,s 3427.86 ± 1.74 which are in good agreement with the perturbative QCD predictions for the Gross—Llewellyn-Smith sum rule in the next-to-leading and next-to-next-to-leading order.
