Transverse target-spin asymmetry associated with DVCS on the proton and a resulting model-dependent constraint on the total angular momentum of quarks in the nucleon
Abstract
Results are reported on the transverse target-spin asymmetry associated with deeply virtual Compton scattering on the proton, extracted from the data accumulated by the HERMES experiment in the years 2002-2004. By comparing the HERMES results and theoretical predications based on a phenomenological model of generalized parton distributions, a model-dependent constraint on the total angular momentum carried by quarks in the nucleon is obtained.
