WebRules for Drawing Feynman Diagrams (version one) The horizontal direction is the horizontal direction, increasing from left to right. The vertical direction represents all other spatial directions. The left side of the diagram represents the initial state, and the right side represents the final state.

FeynDiagram is a library of C++ routines that allows you to draw high-quality PostScript Feynman diagrams by writing a short C++ program to describe the diagram (ie. where the vertices and lines go). Knowledge of C++ is not necessary, but a ...

WebOct 5, 2024 · For virtual particles in Feynman diagrams you have to think like a topologist and be willing to slide things around. In your diagram the left-side/electron vertex is at earlier time than the positron vertex. The diagram where the positron is on the left is the same diagram. The diagram where the electron vertex happens second is also the … WebOct 8, 2024 · I don't know what you mean with "rigorously" determine the Feynman diagrams that contribute to a process. In general from a theoretical point of view you can have two approaches. 1)The hamiltonian approach in interaction picture, thorugh Dyson expansion. 2)The path integral formalism.

WebFeynman Diagrams. Feynman diagrams are a clear way of representing particle interactions in terms of their incoming and outgoing particles and exchange particles. Although there are many variations of Feynman diagrams, they follow a set of rules: The vertical axis represents time. The horizontal axis represents space. http://feyndiagram.com/
