Abstract

We taylor previously introduced methods for isolating individual quark helicity projection nucleon fluctuations by parametrizing projected matrix elements. We then write down the overlap representation of Generalized Parton Distributions (GPDs) in terms of definite quark orbital angular momentum Light Front Wave Functions. We proceed to express nucleonic Parton Distribution Functions, Electromagnetic Form Factors, and the expectation value of the electromagnetic radius as limits and sum rules of these GPDs.
