WebMar 26, 2024 · Sorted by: 1. Drawing the most appropriate Feynman diagram can be a little tricky sometimes. I find it best to work backwards with the general rule of thumb being to try to minimize the number of vertices. We know that the lepton pair l +, ν l must come from a W + boson as that's the only mediator that conserves charge and can violate flavor. WebNov 1, 2024 · Feynman diagrams are designed as a way both to illustrate those electromagnetic interactions, and to explore and quantify the many variants that the strange nature of quantum physics provides that would not be expected otherwise. On the diagrams, matter particles are represented by straight lines and photons as wiggly lines.
