The skewed quark distribution of the pion at large momentum transfer

Abstract

We derive an explicit and model-independent representation for the skewed quark distribution of the pion in the limit of large momentum transfer. Our result is expressed in terms of the conventional pion distribution amplitudes and complies with known properties of skewed parton distributions such as symmetry and polynomiality conditions. The continuity of the result at the points \pm \xi is manifest, whereas its derivatives exhibit discontinuities.
