Deeply Virtual Compton Scattering off the neutron

Nuclear Experiment 2019-08-13 v2

Abstract

The present experiment exploits the interference between the Deeply Virtual Compton Scattering (DVCS) and the Bethe-Heitler processes to extract the imaginary part of DVCS amplitudes on the neutron and on the deuteron from the helicity-dependent D(e,eγ)X({\vec e},e'\gamma)X cross section measured at Q2Q^2=1.9 GeV2^2 and xBx_B=0.36. We extract a linear combination of generalized parton distributions (GPDs) particularly sensitive to EqE_q, the least constrained GPD. A model dependent constraint on the contribution of the up and down quarks to the nucleon spin is deduced.
