Photon electroproduction off nuclei in the ∆-resonance region

نویسنده

  • B. Pasquini
چکیده

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.

Color Transparency at Low Energies: Predictions for JLAB

The study of color transparency (CT) in elastic electroproduction of vector mesons off nuclei encounters the problem of the onset of coherence length (CL) effects. The problem of CT-CL separation arises especially at medium energies, corresponding to HERMES experiment, when the coherence length is of the order of the nuclear radius RA. Only at asymptotic large energies, corresponding to large C...

Exciting pions in nuclei: DCX and Electroproduction in the resonance region

We describe the double charge exchange (DCX) reaction of pions with different nuclear targets at incident kinetic energies of 120 − 180 MeV within the GiBUU transport framework. The DCX process is highly sensitive to details of the interactions of pions with the nuclear medium and, therefore, represents a major benchmark for any model of pion scattering off nuclei at low and intermediate energi...

Incoherent Ρ 0 Electroproduction off Nuclei Typeset Using Revt E X

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...

1 5 Se p 20 08 Inclusive results for electron and photon scattering in the resonance region

We present a model for electron scattering off nuclei and photon absorption in the resonance energy region (W ≦ 2 GeV). The elementary γ/γ ⋆ N-vertex is described using in-medium kine-matics and up-to-date form factors for QE-scattering, π-production form-factors and resonance helicity amplitudes of the MAID analysis. We find good agreement with inclusive data on electron scattering off Oxygen....
