Binding effects in coherent π0 photoproduction on deuterium

Coherent Pion Photoproduction on Deuterium

Differential cross sections of the γd → dπ 0 reaction were measured at photon beam energies between 0.5 and 2.0 GeV over a wide angular range in the CM system. The experiment was performed in Hall B at Jefferson Lab using the CLAS detector. The excitation function, especially at backward CM scattering angles, has been studied with regard to effects due to intermediate on-shell η and ω rescatter...

COHERENT PHOTOPRODUCTION OF THE q " MESON FROM DEUTERIUM

Coherent Photoproduction from Nuclei

We argue that study of the cross section of coherent photo(electro) production of vector mesons off nuclear targets provides an effective method to probe the leading twist hard QCD regimes of color transparency and perturbative color opacity as well as the onset of black body limit (BBL) in the soft and hard QCD interactions. In the case of intermediate energies we use the Generalized Vector Do...
