Abstract

We present a general method for the solution of the renormalization group equations for the non-forward parton distributions on the two-loop level inthe flavour singlet channel based on an orthogonal polynomial reconstruction. Using this formalism we study the effects of the evolution on recently proposed model distribution functions. (C) 1999 Elsevier Science B.V.
