!Name or phenomenon !Description !Diagram |
| Beta decay
| beta particle is emitted from an atomic nucleus | 200px |
| Compton scattering
| scattering of a photon by a charged particle |
| Neutrino-less double beta decay
| If neutrinos are Majorana fermions (that is, their own antiparticle), Neutrino-less double beta decay is possible. Several experiments are searching for this. | 200px |
| Pair production and annihilation
| In the Stückelberg–Feynman interpretation, pair annihilation is the same process as pair production | 200px |
| Møller scattering
| electron-electron scattering |
| Bhabha scattering
| electron-positron scattering | 200px |
| Penguin diagram
| a quark changes flavor via a W or Z loop | 200px |
| Tadpole diagram
| One loop diagram with one external leg |
| Self-interaction or oyster diagram

| One of the many cancellations to the quadratic divergence to squared mass of the Higgs boson which occurs in the MSSM. | 200px |
| Primakoff effect
| production of neutral pseudoscalar mesons by photons interacting with an atomic nucleus | 200px |
| Delbrück scattering
| deflection of high-energy photons in the Coulomb field of nuclei |
