One Loop Chiral Corrections to Hard Exclusive Processes:I. Pion Case
N. Kivel ; M.V. Polyakov ;
Date:	28 Mar 2002
Subject:	hep-ph
Abstract:	We computed the leading non-analytic chiral corrections to the generalized parton distributions (GPDs) of the pion and to the two-pion distribution amplitudes. This allows us to obtain the corresponding corrections for the hard exclusive processes, such as gamma^* gamma -> pi pi, gamma^* N -> 2pi N’ and deeply virtual Compton scattering on the pion target.
