Nucleon Gravitational Form Factor studies at the EIC
ORAL
Abstract
We demonstrate the potential of low center of mass and high luminosity data at the Electron Ion Collider to constrain Nucleon Gravitational Form Factors (GFFs), using Deeply Virtual Compton Scattering (DVCS). The Energy Momentum Tensor is parameterized by three GFFs corresponding to the distributions of mass, angular momentum, and spatial distributions forces. We will focus our discussion on expected constraints to the pressure and shear force distributions, which together translate into normal and tangential force distributions. We perform local fits to Compton Form Factors (CFFs) using pseudo data generated according to current detector designs, and explore the expected kinematical phase space coverage. We also discuss how the availability of a positron beam at the EIC can further help reduce systematic uncertainties in the extraction of the real part of the DVCS amplitudes.
