Large Nf calculations in deep inelastic scattering
J. F. Bennett, J. A. Gracey
Abstract
We describe the evaluation of the anomalous dimensions of twist-2 deep inelastic light cone operators to O(1/Nf) as a check on future perturbative calculations. In particular we present recent results for the singlet gluonic operator dimension in polarised and unpolarised scattering and give three loop predictions for the O(1/Nf) gluonic eigenoperator. The section of the 3-loop O(1/Nf) DGLAP splitting function proportional to the adjoint quadratic Casimir is also calculated for the singlet gluonic operators.
