Explore the concept of angular momentum in lattice quantum chromodynamics through this informative lecture by Nilmani Mathur. Delve into the challenges and techniques of studying angular momentum on a discrete lattice structure, which is crucial for understanding hadron structure and spin. Learn how lattice QCD calculations can provide insights into the distribution of angular momentum among quarks and gluons within hadrons, a key area of investigation for the upcoming Electron-Ion Collider. Gain knowledge on the latest developments in lattice methods for probing nucleon spin structure and their relevance to experimental measurements at facilities like the EIC.
