Yang–Mills theory

Yang–Mills Theory is like a mathematical game you can play with things called 'particles'. The game has a few rules, and when you play it, you can figure out what certain kinds of particles do. It can also help you understand how particles interact with each other. The game's rules are based on something called 'symmetry', which is when things stay the same (like a reflection in a mirror) even if you change how you look at them. Yang–Mills Theory is important for scientists who study particles, especially those who are looking for the Higgs boson.
