Next-next-to-leading QCD approximation for non-singlet moments of deep inelastic structure functions

摘要

We obtain the analytic next-next-to-leading perturbative QCD corrections in the leading twist approximation for the moments N = 2, 4, 6, 8 of the non-singlet deep inelastic structure functions F(sub 2) and F(sub L). We calculate the three-loop anomalous dimensions of the corresponding non-singlet operators and the three-loop coefficient functions of the structure function F(sub L). (orig.).
