Abstract Lepton scattering is an established ideal tool for studying inner structure of small particles such as nucleons well nuclei. As a future high energy nuclear physics project, Electron-ion collider in China (EicC) has been proposed. It will be constructed based on upgraded heavy-ion accelerator, High Intensity Accelerator Facility (HIAF) which currently under construction, together with new electron ring. The proposed provide highly polarized electrons (with polarization ∼80%) and protons ∼70%) variable center mass energies from 15 to 20 GeV the luminosity (2–3) × 10 33 cm −2 · s −1 . Polarized deuterons Helium-3, unpolarized ion beams Carbon Uranium, also available at EicC. main foci EicC precision measurements nucleon sea quark region, including 3D tomography nucleon; partonic nuclei parton interaction environment; exotic states, especially those heavy flavor contents. In addition, issues fundamental understanding origin could addressed by quarkonia near-threshold production order achieve above-mentioned goals, hermetical detector system cutting-edge technologies. This document result collective contributions valuable inputs experts across globe. program complements ongoing scientific programs Jefferson Laboratory EIC project United States. success this advance both particle accelerator technology China.
