Electroproduction 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 کاملelectroproduction 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 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 ...
متن کاملPhoton electroproduction off nuclei in the ∆-resonance region
The cross section for the A(e, eγ)A reaction is calculated, investigating the contribution from the nuclear target with respect to the radiative corrections from the electron. The reaction mechanism is studied for photon emission in the ∆-resonance region, varying the scattering geometry and analyzing the most favourable kinematical conditions to extract information on the nuclear system. PACS ...
