Comments on ep and e\mu elastic scattering |
E. A. Kuraev and E. Tomasi-Gustafsson |
In this note we prove that the contribution of the box diagram calculated for electron muon elastic scattering can be considered an upper limit to electron proton scattering. As an exact QED calculation can be performed, this statement is useful for constraining model calculations involving the proton structure. |
