We present the first measurements of the e[over -->]p-->epgamma cross section in the deeply virtual Compton scattering (DVCS) regime and the valence quark region. The Q(2) dependence (from 1.5 to 2.3 GeV(2)) of the helicity-dependent cross section indicates the twist-2 dominance of DVCS, proving that generalized parton distributions (GPDs) are accessible to(More)
We propose to study Deep Virtual Compton Scattering (DVCS) using the CEBAF 6 GeV polarized electron beam and the CLAS detector at Jefferson Lab. The main focus of the experiment will be measurement of the beam spin asymmetry in the reaction ep → epγ. This asymmetry is directly proportional to the imaginary part of the DVCS amplitude and gives access to a(More)
A measurement of the electroproduction of photons off protons in the deeply inelastic regime was performed at Jefferson Lab using a nearly 6 GeV electron beam, a longitudinally polarized proton target, and the CEBAF Large Acceptance Spectrometer. Target-spin asymmetries for ep→e^{'}p^{'}γ events, which arise from the interference of the deeply virtual(More)
We propose to use the incident beam energy dependence of the Bethe-Heitler (BH) and deeply virtual Compton scattering (DVCS) amplitudes to isolate the BH·DVCS interference term from the pure DVCS 2 contribution to the photon electroproduction (ep → epγ) cross section in the deeply virtual regime. This is a necessary step in order to extract meaningful(More)
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,e'gamma)X cross section measured at Q2=1.9 GeV2 and xB=0.36. We extract a linear combination of generalized(More)
The beam-spin asymmetries in the hard exclusive electroproduction of photons on the proton (e p-->epgamma) were measured over a wide kinematic range and with high statistical accuracy. These asymmetries result from the interference of the Bethe-Heitler process and of deeply virtual Compton scattering. Over the whole kinematic range (x(B) from 0.11 to 0.58,(More)
