Generalized parton distributions through universal moment parameterization: zero skewness case

A bstract We present a global analysis program for the generalized parton distributions (GPDs) based on conformal moment expansion. apply strategy of universal parameterization to fit both collinear distribution functions (PDFs) from phenomenology and form factors lattice calculations, show that is flexible enough accommodate these constraints. In addition, we can also direct calculations GPDs large-momentum effective theory. this work focus t -dependent PDFs which correspond in ? ? 0 limit. The applies ? region with extra parameters, therefore be fitted experimental observables future. With demonstrative example GPDs, exhibit quark transverse angular momentum densities proton as well impact parameter space quarks unpolarized transversely polarized protons.
