So the muon going along spits off a photon, then reabsorbs it. That is a Feynman diagram that contributes to the following process. Muon becomes a muon. So the muon is just traveling along through space. But there's all these buzzing fields around it, which we discuss using Feynman diagrams. There are also diagrams where the muon spits out a photon and eventually reabsorbs it.
