WebThe diagrams show the possible ways in which particles can interact with each other through the exchange of other particles. For example, a Feynman diagram can show how two electrons repel each other through the exchange of a photon, or how a proton can decay into a neutron, a positron, and a neutrino through the exchange of a W boson. 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. board nomination letter templateWebThis process, called beta decay, is important in many physical processes. A Feynman diagram of beta decay is given in Figure 11.14(a). The neutron emits a W − W − and becomes a proton, then the W − W − produces an electron and an antineutrino. This process is similar to the scattering event board nomination letter
