Description
In this talk I will focus on the asymmetry ALT involving a longitudinally polarized electron or proton colliding with a transversely polarized proton, with a single pion, photon, or jet detected in the final state. We provide rigorous numerical predictions for Jefferson Lab, COMPASS, RHIC, and the future Electron-Ion Collider using recent extractions of the parton distribution functions (PDFs) and fragmentation functions (FFs) involved in calculating ALT. Uncertainty bands are generated through a bootstrapping method that randomly selects PDF/FF replicas with replacement until the computation converges. Through these predictions we hope to motivate future measurements that can help us gain more insight into the quark-gluon-quark interactions that occur inside of hadrons as well as dynamical quark mass generation in QCD.
