Low-x Physics at a Future Electron-Ion Collider (EIC) Facility

The proposed polarized electron-ion collider (EIC) will allow for precision exploration of various novel aspects of QCD including low-x phenomena, the spin structure of the proton, and gluon saturation in heavy nuclei. As this project gains momentum, it is increasingly important for the QCD community to understand quantitatively the kinematic reach and expected sensitivities for various measurements. We briefly summarize key accelerator design parameters and then focus on expected measurement sensitivities, thus exposing how the EIC will allow an extension of the successful HERA program into exciting new regimes.
