Evaluating Radiative Corrections in Super Rosenbluth Experiments

POSTER

Abstract

Electron-proton elastic scattering experiments have mapped out the proton's electromagnetic form factors, i.e., how the proton's electric charge and current are distributed within its volume. Nevertheless, there are some inconsistencies in our determinations of these form factors, especially at high-momentum transfer. In this project, we are trying to determine the impact of radiation emitted by charged particles in collisions, a topic known as "Radiative Corrections," in a class of experiments called Super Rosenbluth experiments. We ran Monte Carlo simulations to conduct a Super Rosenbluth pseudo-experiment using several commonly used radiative corrections approximations in order to evaluate their suitability. We find that when using the Peaking Approximation, the radiative corrections in Super Rosenbluth experiments are smaller and less kinematics-dependent than in equivalent Rosenbluth experiments. However, this is not necessarily true when using more sophisticated models, calling into question the assumed advantages of the Super Rosenbluth technique.
