Elastic ep scattering and higher radiative corrections

Higher order correction in the ep scattering will be discussed. In particular the second order Born correction to the electron scattering off Coulomb potential will be derived. Various possible shapes of the charged distribution inside the proton will be discussed. Then I will evaluate the “box” contribution to the ep scattering, assuming that the intermediate state is given by the virtual nucleon. The theoretical results will be compared with the model independent prediction of the higher order contribution obtained with the neural networks. Eventually I will show the prediction of proton radius.
