electroproduction off nuclei
In the present paper we investigate incoherent ρ 0 electroproduction off complex nuclei. We derive a novel, simple expression for the incoherent elec-troproduction cross section in which one can clearly separate the final state interactions of the reaction products from the 'initial state interactions' of the photon that give rise to nuclear shadowing. In the special case of purely absorptive f...
متن کاملElectroproduction of Charmonia off Protons and Nuclei
Elastic virtual photoproduction of charmonia on nucleons is calculated in a parameter free way with the light-cone dipole formalism and the same input: factorization in impact parameters, light-cone wave functions for the photons and the charmonia, and the universal phenomenological dipole cross section which is fitted to other data. The charmonium wave functions are calculated with four known ...
متن کاملCoherence Effects in Diffractive Electroproduction from Nuclei
We argue that study of the cross section of coherent photo(electro) production of ρ, ρ, ...-mesons provides an effective method to probe onset of black body limit(BBL) in the soft and hard QCD interactions. We illustrate the expected features of the onset of BBL using generalized vector dominance model(GVDM). We show that this model describes very well ρ-meson coherent photoproduction at 6 ≤ Eγ...
متن کاملHigh energy electroproduction off complex nuclei
We investigate hadron attenuation in deep-inelastic lepton scattering off complex nuclei in the kinematic regime of the HERMES experiment. Our transport theoretical simulations reveal strong prehadronic final state interactions of the reaction products with the surrounding nuclear medium early after the initial γ∗N interaction has taken place. In this work we compare our model results with the ...
