that an EIC would bring would have direct impact on particle physics, and improve our understanding of the most beautiful of all Yang Mills theories, QCD.1 Design and construction of an EIC would keep the United States at the forefront of new collider technologies. An EIC would contribute to basic energy sciences through the EIC goal of understanding the emergent behavior of dense gluonic systems, and to plasma physics and astrophysics, through the creation of a state with enormous but saturated gluon density, resembling but differing from the radiation dominated plasmas of explosive astrophysics.

During its deliberations, the committee studied long-range plans in nuclear and particle physics relevant to EIC science, not only in the United States but also in the Asian and European communities, and surveyed existing and planned facilities around the world that can address science similarly to an EIC. Accelera tor and collider experts from the United States and the international community were consulted.

In addition to highly polarized beams, high luminosity -- as shown in Figure 7.1 -- is needed to answer, by means of imaging, the question of how the spin and mass of the nucleon arise; and a high and variable center-of-mass energy, as shown in Figure 7.1 is essential to understanding the nature of gluons in nuclei. As the figure indicates, an EIC would also be useful in studying nuclear structure in terms of quarks and gluons -- with the gluon saturation region explored at highest energies.

The EIC is the only high-energy collider being planned for construction in the United States. Furthermore, its high design luminosity and highly polarized beams would push the frontiers of accelerator science and technology.

An EIC would have impact on other research areas including particle physics, astrophysics, theoretical and computational modeling as well as rich intellectual connections to atomic and condensed matter physics. Lastly, with the exciting physics frontier program enabled by an EIC, nuclear science will continue to attract outstanding graduate students, more than half of whom will go on to science, technology, engineering, and mathematics jobs in in dustry and DOE National Nuclear Security Administration and Office of Science laboratories.
