Anomalous dimension of gluonic operator in polarized deep inelastic scattering at O(1/Nf)
J. F. Bennett, J. A. Gracey
Abstract
We compute the O(1/Nf) correction to the predominantly gluonic flavour singlet twist-2 anomalous dimension used in polarized deep inelastic scattering. It is consistent with known two loop perturbation theory and we determine the three loop contribution at O(1/Nf). The treatment of the epsilon-tensor in the large Nf d-dimensional critical point formalism is also discussed.
