Abstract:
Massless gluons and almost massless quarks, through their interactions, generate most of the mass of the nucleons. Without gluons, there would be no nucleons, no nuclei, no visible universe. Despite many decades of experimental and theoretical advances in QCD, the exact role the gluons play that results in the nucleon and nuclear structure and their properties is un-understood. Currently operating facilities and their future upgrades are unlikely to address them. A new electron-proton, electron-ion collider with high-energy, high-luminosity and polarized beams was recently recommended by the US Nuclear Science Advisory Committee (NSAC) to address those important unanswered questions. I will discuss the science of this future facility and present the status of the project.
