WebIn the anhiliation process you have two vertices with photons. It means there is a virtual electron/positron involved in the process. So I suppose in some sense, you can have spontanious pair production but it requires the electron-positron pair produced are virtual, and hence short lived. – user3728501 Jun 18, 2024 at 12:10 WebWe would like to show you a description here but the site won’t allow us. flywheel vs rear wheel horsepower

"If either the electron or positron, or both, have appreciable kinetic energies, other heavier particles can also be produced (such as D mesons or B mesons), since there is enough kinetic energy in the relative velocities to provide the rest energies of those particles. Alternatively, it is possible to produce photons and other light particles, but they will emerge with higher kinetic energies. " - Can photons combine
