Generalized Parton Distributions: A New Avenue to Color Transparency Phenomena

Abstract

Color Transparency studies have been since long suggested as a means to study the occurrence and relevance of small size hadronic configurations, predicted within QCD to dominate exclusive scattering processes, by monitoring the passage of hadrons through the nuclear medium at large four momentum transfer, $Q^2$. The validation through experiments of this picture -- the dominance of short separation components -- is however not straightforward. This situation motivated us to explore a description of Color Transparency in terms of Generalized Parton Distributions (GPDs) using a recent interpretation in impact parameter representation.
