The 16th moment of the non-singlet structure functions $F_2(x,Q^2)$ and $F_L(x,Q^2)$ to $O$($\alpha^3_S$)

Abstract We present the results of an analytic next-to–next-to leading order QCD calculation of the non-singlet anomalous dimension γ 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.
