Spin-Dependent DIS from Polarized $^3$He at EIC
Abstract
A day-1 EIC detector should be prepared to carry out inclusive DIS measurements from electron collisions with nucleon and nuclear beams. Here I consider the scientific motivation for spin-dependent DIS measurements from a polarized He beam. Longitudinally polarized He ions can be used to measure in purely inclusive scattering. I also consider spin-dependent DIS from polarized He by tagging the spectator proton or deuteron in coincidence with the scattered electron. A calculation of high energy scattering from the polarized He nucleus in the EIC frame is motivated. Further, this type of measurement can be extended to other polarized few-body nuclei. High energy spin-dependent scattering from polarized He with tagged proton and deuteron could be studied experimentally ahead of EIC using spin-dependent proton-He scattering in RHIC, when polarized He ions become available.
