With QED covered, it's time to move on the quantum chromodynamics, or QCD. This is the QFT that governs the strong nuclear force, so it explains the behavior and interaction of quarks through mediator bosons known as gluons. What are the symmetries involved for QCD? What are quarks exactly? What is color charge? How can we create Feynman diagrams for this model? Let's talk about it!
