Forward Pseudoscalar Meson Electroproduction Above the Resonance Region
A principal motivation for studying exclusive reactions is that they provide a new class of observables, called o -diagonal parton distributions, for the internal structure of the nucleon. The internal structure of the nucleon has been studied through inclusive scattering of high energy leptons in the deep inelastic scattering (DIS) limit. Polarized DIS measurements of g1(x;Q ), or the relevant...
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 ...
متن کاملProbing nucleon strangeness structure with φ electroproduction
We study the possibility to constrain the hidden strangeness content of the nucleon by means of the polarization observables in φ meson electroproduction. We consider the OZI evading direct knockout mechanism that arises from the non-vanishing ss̄ sea quark admixture of the nucleon as well as the background of the dominant diffractive and the oneboson-exchange processes. Large sensitivity on the...
متن کاملNew Predictions for Electroproduction Amplitudes in the Resonance Region
The role played by orbital angular momentum Lz in parton models at P =m is delineated. By postulating similar behavior for parton wave functions of equal L z, we are able to relate the electroexcitation form factors of the low-lying resonances to the elastic form factors of the nucleon.
متن کاملProbing nucleon strangeness in φ electroproduction
The subject of the strangeness content of the nucleon and nuclei has been one of the important issues in hadron and nuclear physics [1]. Production of φ meson from nucleon target has been suggested as a sensitive probe to study the strangeness content of the nucleon. Because of the ideal mixing with ω, φ meson is nearly a pure ss̄ state and its direct coupling to the nucleon must be suppressed b...
