Title: Spin Alignment of Quarks In the Nucleus
Abstract: I will describe upcoming measurements with the CLAS12 detector at JLab, which aim to provide the first measurements of nuclear effects on the spin structure of bound protons - a completely unexplored area. These measurements will use a longitudinally polarized lithium-7 target and an 11 GeV polarized electron beam. I will discuss the physics motivations and the expected performance of the experiment for both inclusive and semi-inclusive scattering. Additionally, I will outline how these measurements could inform future upgrades for the EIC. I will also describe planned measurements of Lambda particles using the ePIC Zero-degree calorimeter. Lambda studies will be a unique tool, including for merging spin-related studies with studies of cold nuclear matter at the EIC.
