QCD Sum Rules and Models for Generalized Parton Distributions
arXiv:hep-ph/0410153 · doi:10.1002/andp.200410114
Abstract
I use QCD sum rule ideas to construct models for generalized parton distributions. To this end, the perturbative parts of QCD sum rules for the pion and nucleon electromagnetic form factors are interpreted in terms of GPDs and two models are discussed. One of them takes the double Borel transform at adjusted value of the Borel parameter as a model for nonforward parton densities, and another is based on the local duality relation. Possible ways of improving these Ans{ä}tze are briefly discussed.
