Deeply virtual Compton scattering off nuclei
We consider the hard leptoproduction of a photon off nuclei up to spin-1. As a new result we present here the general azimuthal angular dependence of the differential cross section for a spin-1 target. Its twist-two Fourier coefficients of the interference and squared deeply virtual Compton scattering amplitude are evaluated in leading order approximation of perturbation theory in terms of gene...
متن کاملDeeply Virtual Compton Scattering off Nuclei
Deeply virtual Compton scattering (DVCS) is the golden exclusive channel for the study of the partonic structure of hadrons, within the universal framework of generalized parton distributions (GPDs). This paper presents the aim and general ideas of the DVCS experimental program off nuclei at the Jefferson Laboratory. The benefits of the study of the coherent and the incoherent channels to the u...
متن کاملDeeply Virtual Compton Scattering on Spin-1 Nuclei
We consider the Generalized Parton Distributions for spin-1 nuclei in general and on the deuteron in particular. We use the impulse approximation to obtain a convolution model for them. Sum rules are used to check the validity of the approach and to estimate the importance of higher Fock-space states in the deuteron. Numerical predictions for the Beam Spin Asymmetry in deeply virtual Compton sc...
متن کاملMesonic Contribution to the Compton Scattering Amplitude for Heavy Nuclei
The contribution of mesonic exchange currents to nuclear Compton scattering is investigated within the framework of a Fermi gas model of nuclear matter in the non-relativistic limit. The additional interaction between the nucleons is accounted for by including twoand threebody diagrams. As a test of this model, the enhancement constant κ is calculated. The full correlators for the central and t...
متن کاملCoherent Compton scattering on light nuclei in the ∆-resonance region
Coherent Compton scattering on light nuclei in the ∆ resonance region is studied in the impulse approximation and is shown to be a sensitive probe of the in-medium properties of the ∆ resonance. The elementary amplitude on a single nucleon is calculated from the unitary K-matrix approach developed previously. Modifications of the properties of the ∆ resonance due to the nuclear medium are accou...
