Nonforward Parton Distributions

Abstract

Applications of perturbative QCD to deeply virtual Compton scattering and hard exclusive electroproduction processes require a generalization of usual parton distributions for the case when long-distance information is accumulated in nonforward matrix elements 〈p|O(0, z)|p〉 of quark and gluon light-cone operators. We describe two types of nonperturbative… (More)
