Prospects for Studies of Short-Range Correlations in Nuclei at the Future Electron-Ion Collider

ORAL

Abstract

Quantum Chromodynamics (QCD) provides the framework for understanding the strong nuclear force. However, due to the nature of nuclear dynamics, our understanding of the dynamical forces between nucleons in a nucleus is as-of-yet incomplete. The EMC effect describes the suppression of the ratio of the structure function, $F_{2}$, between a heavy nucleus and a deuteron for x \textgreater .3. Short-range correlations (SRCs) were proposed as one possible explanation of the EMC Effect, making the study of SRCs valuable for understanding QCD. SRCs are best studied in e$+$A collisions, either using a fixed target, or an e$+$A collider. In January 2020, CD-0 was approved for an Electron-Ion Collider (EIC) at Brookhaven National Laboratory. The EIC will enable collisions of electrons with a wide range of nuclei at a range of center of mass energies, enabling detailed study of SRCs. In this talk, I describe a new study of SRCs using the novel e$+$A MC event generator, BeAGLE. In particular, we use BeAGLE to study the sensitivity of observables to high internal nucleon momentum via incoherent diffractive J/Psi vector meson production. By tagging the spectator nucleon from the deuteron breakup in full EIC detector simulations in the far-forward region ($\Theta $ \textless 2$^{\mathrm{o}})$ access to the SRCs in the deuteron is assessed.
