Generalized parton distributions in AdS/QCD
arXiv:1010.2815 · doi:10.1103/PhysRevD.83.036001
Abstract
The nucleon helicity-independent generalized parton distributions (GPDs) of quarks are calculated in the zero skewness case, in the framework of the AdS/QCD model. The present approach is based on a matching procedure of sum rules relating the electromagnetic form factors to GPDs and AdS modes.
