Feynman Diagrams and the Higgs Boson: An IB Physics Introduction, Cheat Sheet of Physics

This document offers a concise introduction to feynman diagrams and their application in representing particle interactions, specifically focusing on the higgs boson within the context of ib physics. it uses visual aids and examples to illustrate key concepts such as particle annihilation and pair production, making it an excellent resource for high school students studying atomic physics and the standard model. The diagrams clearly show particle interactions over time, and the inclusion of conservation laws adds depth to the explanation.
