title = "Two-loop effects in the evolution of non-forward distributions",
abstract = "We study the effects of next-to-leading order corrections on the evolution of the twist-two non-forward parton distribution functions in the flavour non-singlet sector. It is found that the deviation from leading order evolution is small for all values of the parton momentum fraction variable for moderately large values of the scale parameter.",

note = "Funding Information: One of us (A.B.) would like to thank A.V. Radyushkin for useful correspondence and providing some of his results on the model of the non-forward distributions before publication. He also what to thank G.P. Korchemsky and B. Pire for useful conversations and O.V. Teryaev for discussions about the positivity constraints for non-forward distributions. A.B. is grateful to G.P. Korchemsky and D. Schiff for the hospitality at LPTHE (Orsay) and B. Pire at {\'E}cole Polytechnique. A.B. was supported by the Alexander von Humboldt Foundation and partially by Russian Foundation for Fundamental Research, grant N 96-02-17631. ",
