Query: Large N_f methods for computing the perturbative structure of deep
  inelastic scattering   The large N_f self consistency method is applied to the computation of
perturbative information in the operator product expansion used in deep
inelastic scattering. The O(1/N_f) critical exponents corresponding to the
anomalous dimensions of the twist 2 non-singlet and singlet operators are
computed analytically as well as the non-singlet structure functions. The
results are in agreement with recent explicit perturbative calculations.
