Two-photon Exchange in Electron-proton Elastic Scattering: Theory Update
Recent theoretical developments in the studies of two-photon exchange effects in elastic electron-proton scattering are reviewed. Two-photon exchange mechanism is considered a likely source of discrepancy between polarized and unpolarized experimental measurements of the proton electric form factor at momentum transfers of several GeV. This mechanism predicts measurable effects that are current...
متن کاملObservables in elastic electron-deuteron scattering with two-photon exchange
The general form of the cross section as well as the polarizations of electron-deuteron elastic scattering are given. Two-photon exchange effects are analyzed. Possible signatures of the two-photon exchange effects in the electron-deuteron elastic scattering are discussed. PACS: 13.40.GP, 25.30.-c, 25.30.Bf, 24.70.+s, 13.60.Fz
متن کاملTwo - Photon Exchange in Electron - Deuteron Scattering
We show that multiple scattering of the electron (i.e., two-photon exchange) in electron-deuteron elastic scattering leads to a small component in the cross section, which decreases very slowly with momentum transfer, and may dominate the cross section at high momentum transfer.
متن کاملIs there model-independent evidence of the two-photon-exchange effect in the electron-proton elastic scattering cross section?
We analyze the data of the elastic electron proton scattering to look for modelindependent evidence of the two-photon-exchange (TPE) effect. We fix the value of R = GE/GM as determined from the data of the polarization transfer experiment and parametrize the TPE contribution in forms which are consistent with the constraint derived from crossing symmetry and the charge conjugation. In contrast ...
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...
