The 16th Moment of the Non--Singlet Structure Functions $F_2(x,Q^2)$ and $F_L(x,Q^2)$ to $O({\alpha }_s^3)$

Abstract

We present the results of an analytic next--to--next--to leading order QCD calculation of the non--singlet anomalous dimension ${\gamma }_{\mathrm{NS}}^{+}(N)$ and the coefficient functions $C_{2,L}(N)$ associated to the deeply inelastic structure functions $F_2(x,Q^2)$ and $F_L(x,Q^2)$ for the Mellin moment N=16. Comparisons are made with results in the literature.
