WebFeynman Diagrams. Feynman diagrams are graphical ways to represent exchange forces. Each point at which lines come together is called a vertex, and at each vertex one may examine the conservation laws which govern particle interactions. Each vertex must conserve charge, baryon number and lepton number. WebFeynman diagrams (named after theoretical physicist Richard P. Feynman) are found in almost every paper published by ATLAS and are a powerful tool to visually represent …
