As one of his first examples, he considered the problem of electron-electron scattering. He drew a simple diagram on the blackboard, similar to the one These diagrams, therefore, portray what is “really” happening, and provide a convenient way to catalogue the various possible processes of creation, annihilation, and exchange. The key points of a Feynman diagram are the “vertices,” representing those spacetime points at which (in this example) photons are created or absorbed. Feynman Diagrams and the Strong Force. At the most fundamental level, the strong force is an exchange force between quarks mediated by gluons.The use of Feynman diagrams to visualize the strong interaction involves primitive vertices with quarks and gluons. Feynman diagrams can be used everywhere in a LaTeX document, in particular in centered | for creating graphical equations like the one in figure .

Figure 1: Feynman diagram for two different decays. The Feynman diagram for D0 → K− + π+ is. D. What people say about us. I really liked how every topic is broken down and explained. The use of examples that are easy to understand, and then the TikZ-Feynman: A package I created to make Feynman diagram in LaTeX. I tried my best to make the examples in the README.md as clear as possible.

Approx size of matrix element may be estimated from thesimplest valid Feynman Diagram for given process. Full matrix element requires in nite number of of writing the same Feynman diagram. On the other hand, changing the way in which the lines in a diagram are connected to one another does however result in a new diagram. Consider for example the process e+ + e !
