Resumen:
The electromagnetic form factors of the proton and neutron encode information on the spatial structure of their charge and magnetization distributions. Electron-proton scattering has been studied extensively with hydrogen targets. I will discuss the Rosenbluth, Super-Rosenbluth and polarization techniques used to study the proton and the disagreement showed by the results. This discrepancy is generally attributed to neglected two-photon exchange (TPE) corrections. I will also discuss the benefits of combining the Super-Rosenbluth technique with positron beam measurements for the understanding of the TPE corrections.
