Novel Rosenbluth Extraction Framework for Compton Form Factors from Deeply Virtual Exclusive Experiments

Abstract

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