Baryon form factors at high momentum transfer and generalized parton distributions

Abstract

Nucleon form factors at high momentum transfer |t| are treated in the framework of generalized parton distributions (GPD's). The possibility of obtaining information about parton high transverse momentum components by application of GPD's to form factors is discussed. This is illustrated by applying an ad-hoc 2-body parton wave function to elastic nucleon form factors F1 and F2, the N to Delta magnetic form factor G*M, and wide angle Compton scattering (WACS) form factor R1.
