The effects of nuclear structure on generalized parton distributions of 3He

Abstract

The effect of the nuclear medium on generalized parton distributions (GPDs) is studied for the 3He nucleus, through a realistic microscopic analysis. In Impulse Approximation, Fermi motion and binding effects, evaluated by modern potentials, are found to be larger than in the forward case and very sensitive to the details of nuclear structure at short distances.Comment: 4 pages, talk given at the Conference "Baryons 2004", October 25-29 2004, Pailaseau (France), to be published by Nuc.
