Novel Rosenbluth extraction framework for Compton form factors from deeply virtual exclusive experiments

We use a generalization of the Rosenbluth separation method for a model independent simultaneous extraction of the Compton Form Factors H and E, from virtual Compton scattering data on an unpolarized target. A precise evaluation of H and E, enabled by the proposed method, is the first step towards pinning down the distribution of angular momentum inside the proton. (C) 2022 The Authors.

Automated summary

We propose a generalization of the Rosenbluth separation method to extract the Compton Form Factors H and E simultaneously from virtual Compton scattering data on an unpolarized target. This precise evaluation of H and E is the first step towards determining the distribution of angular momentum inside the proton.
