The Science
The U.S. nuclear physics community is preparing to build the Electron-Ion Collider (EIC), a flagship facility for probing the properties of matter and the strong nuclear force that holds matter together. The EIC will allow scientists to study how nucleons (protons and neutrons) arise from the complex interactions of quarks and gluons. The EIC will also help scientists examine gluon saturation. This occurs when gluons are densely concentrated at high energy levels. It results in the gluons splitting and recombining at the same rate, balancing out these processes. EIC measurements of this behavior will help answer important questions in physics.
