Two-photon Exchange and Electromagnetic Proton Form Factors
نویسنده
چکیده
The presence of 2γ-exchange in electron proton elastic scattering is discussed. From C-invariance and crossing symmetry, 2γ contribution induces a specific dependence of the reduced cross section on the variable ǫ. No evidence of such dependence exists in the available experimental data.

Two-photon exchange effect on deuteron electromagnetic form factors
Corrections of two-photon exchange to proton and neutron electromagnetic form factors are employed to study the effect of two-photon exchange on the deuteron electromagnetic form factors. Numerical results of the effect are given. It is suggested to test the effect in the measurement of Pz in a small angle limit. PACS: 13.60.Hb,12.38.Aw, 12.38Cy; 12.38.-t; 13.60.Fz, 12.40.Nn
متن کاملExtraction of two-photon contributions to the proton form factors
Significant discrepancies have been observed between proton form factors as measured by Rosenbluth separation and polarization transfer techniques. There are indications that this difference may be caused by corrections to the one photon exchange approximation that are not taken into account in standard radiative correction procedures. In this paper, we constrain the two-photon amplitudes by co...
متن کاملModel Independent Considerations on Two-photon Exchange in Electron Proton Scattering and in the Crossed Processes
The presence of two photon exchange in ep elastic scattering and in the crossed processes (p̄+p ↔ l+l, l = e or μ) is discussed in terms of three complex amplitudes which are functions of two kinematical variables, the momentum transfer squared q and the polarization of the virtual photon, ǫ. Model independent expressions of the differential cross section and of polarization observables are deri...
متن کاملTwo Photon Exchange Contributions to Elastic ep Scattering in the Nonlocal Field Formalism
We construct a nonlocal gauge invariant Lagrangian to model the electromagnetic interaction of proton. The Lagrangian includes all allowed operators with dimension up to five. We compute the two photon exchange contribution to elastic electron-proton scattering using this effective nonlocal Lagrangian. The one loop calculation in this model includes the standard box and cross box diagram with t...
متن کاملOverview of Nucleon Structure Studies ⋆
A brief overview of the recent activity in the measurement of the elastic electromagnetic proton and neutron form factors is presented. It is discussed how the quality of the data has been greatly improved by performing double polarization experiments, and the role of two-photon exchange processes will be highlighted. The spatial information on the quark charge distribibutions in the nucleon re...
