A Feynman diagram is a representation of quantum field theory processes in terms of particle interactions. The particles are represented by the lines of the diagram

Their main use is to calculate the amplitude (or rather itimes the amplitude) for a state with speciﬁed incoming particles with momenta and spins speciﬁed to evolve to a diﬀerent state with speciﬁed particles and their momenta and spins.4 We divide the Lagrangian into 2001-12-10 A Feynman diagram is a diagram that shows what happens when elementary particles collide. Feynman diagrams are used in quantum mechanics. A Feynman diagram has lines in different shapes—straight, dotted, and squiggly—which meet up at points called vertices.

Feynman Diagrams for Beginners arXiv:1602.04182v1 [physics.ed-ph] 8 Feb 2016 Kreimir Se hela listan på feynman.com The Feynman diagrams are much easier to keep track of than "old-fashioned" terms, because the old-fashioned way treats the particle and antiparticle contributions as separate. Each Feynman diagram is the sum of exponentially many old-fashioned terms, because each internal line can separately represent either a particle or an antiparticle.
