The COmpact detectoR for the Eic (CORE) Proposal is prepared in response to the “Call for Collaboration Proposals for Detectors to be located at the Electron-Ion Collider (EIC)”. The CORE detector is designed to satisfy the “mission need” statement with a physics scope that completely and comprehensively covers the one outlined in the EIC Community White Paper [1] and the National Academies of Science (NAS) 2018 report. The distinguishing theme of the CORE detector is that it exploits fully technological advances in detector precision and granularity to minimize the size of the overall detector.
