| THO-PHOTON Exchange and electromagnetic proton form factor |
| E. Tomasi-Gustafsson |
The presence of $2\\gamma$-exchange in electron proton elastic scattering is discussed. From C-invariance and crossing symmetry, $2\\gamma$ contribution induces a specific dependence of the reduced cross section on the variable $\\epsilon$. No evidence of such dependence exists in the available experimental data. |
