Homework: EIC Challenges & Opportunities

1. Homework: EIC Challenges & Opportunities Lessons from Galveston  need to: • DEEPEN the science case and the connections to other forefront science questions (what is transformational about EIC?) e.g., the opportunity to observe systems with gauge boson occupation #’s >> 1 reveals a unique aspect of QCD many-body systems, but does it tell us more? Can saturated gluonic matter illuminate interesting questions in other non-Abelian theories that are more difficult to observe? Why should other scientists or the public care about dense gluonic matter?

2. Homework: EIC Challenges & Opportunities Can one make use of novel parity-violation measure-ment techniques for stored, cooled ions, by observing dependence of ion beam lifetime on e beam helicity? Requires minimal beam losses from other than e-p interactions. • BROADEN the science case -- make it interesting to a wider portion of the nuclear physics community! e.g., is there a viable and compelling electroweak symmetry program? What luminosity would be needed to make interesting measure-ments of the running of the weak coupling below the Z0? Anything interesting to be learned from PV in e-A vs. A? What precision needed?

3. Homework: EIC Challenges & Opportunities EIC? RHIC-II e.g., can one put together a compelling case for ~2 GeV e on 250 GeV p  medium-to-high x via reverse kinematics, with access to forward proton or nucleus fragments? • Think about staging EIC, or an EIC precursor! Even in a budget bursting at an ample seam, there may be pockets of opportunity! IF (NP budget doubles.AND. Stochastic cooling  LRHIC-II) THEN Perhaps some free energy in the profile for an early EIC start…
