Where Do the Proton Mass and Spin Come From?

Streaming Media


I will give a synopsis on Quantum Chromodynamics (QCD) — the fundamental theory of strong interaction, and some of its consequences. Lattice gauge theory is introduced as a practical way of solving the theory through computer simulation with Monte Carlo methods. I will show how the proton mass and spin are divided into their quark and glue components in lattice QCD calculations.
