The Electron-Ion Collider (EIC) is a next-generation accelerator facility being developed at Brookhaven National Laboratory in the United States. Through collisions of electrons with protons and atomic nuclei, it will investigate the quark and gluon structure of matter within quantum chromodynamics (QCD), including the origins of nucleon spin and the dynamics of gluons in nuclei.
With operations anticipated in the mid-2030s, preparations for the EIC physics program are already underway. Experimental groups are developing the ePIC detector and evaluating its physics performance, while theoretical research is advancing through perturbative calculations, lattice QCD, and phenomenological analyses. The coming decade provides an important opportunity to coordinate these efforts in preparation for future measurements.
This workshop aims to review these developments and identify research priorities for the EIC program through focused discussions between theorists and experimentalists. The main topics will include the three-dimensional structure of the nucleon, quark and gluon contributions to its spin, and gluon dynamics. Particular attention will be given to relating theoretical predictions and parton distributions to experimentally accessible observables.
