| Model independent properties of two-photon exchange in elastic electron proton scattering |
| M. P. Rekalo, E. Tomasi-Gustafsson |
We derive from first principles, as the C-invariance of the electromagnetic interaction and the crossing symmetry, the general properties of two-photon exchange in electron-proton elastic scattering. We show that the presence of this mechanism destroys the linearity of the Rosenbluth separation but does not affect the terms related to the electromagnetic form factors. |
