Generalized Parton Distributions of the Proton in Position Space : Zero Skewness
Abstract
We present a study of the parton distributions in transverse position or impact parameter space using a recent parametrization of u and d quark generalized parton distributions (GPDs) H(x,t) and E(x,t) at zero skewness. We make a comparative study between different parametrizations and discuss the region of validity of the positivity condition.
