Measuring Recoiling Nucleons from the Nucleus with the Electron Ion Collider

Understand

Short range correlated nucleon-nucleon ($NN$) pairs are an important part of the nuclear ground state.

• They are typically studied by scattering an electron from one nucleon in the pair and detecting its spectator correlated partner ("spectator-nucleon tagging").
• The Electron Ion Collider (EIC) should be able to detect these nucleons, since they are boosted to high momentum in the lab frame by the momentum of the ion beam.
• To determine the feasibility of these studies with the planned EIC detector configuration, we have simulated quasi-elastic scattering for two electron and ion beam energy configurations: 5 GeV $e^{-}$ and 41 GeV/A ions, and 10 GeV $e^{-}$ and 110 GeV/A ions.
