This is a list of common Feynman diagrams.
Name or phenomenon | Description | Diagram |
---|---|---|
Beta decay | beta particle is emitted from an atomic nucleus |
![]() |
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. |
![]() |
Pair production and annihilation | In the Stückelberg–Feynman interpretation, pair annihilation is the same process as pair production |
![]() |
Møller scattering | electron-electron scattering |
![]() |
Bhabha scattering | electron-positron scattering |
![]() |
Penguin diagram | a quark changes flavor via a W or Z loop |
|
Tadpole diagram | One loop diagram with one external leg |
![]() |
Self-interaction | An electron emits and reabsorbs a photon |
![]() |
Box diagram | The box diagram for kaon oscillations |
![]() |
Photon-photon scattering |
![]() | |
Higgs boson production | Via gluons and top quarks |
![]() |
Via quarks and W or Z bosons |
![]() | |
Quad cancellations | One of the many cancellations to the quadratic divergence to squared mass of the Higgs boson which occurs in the MSSM. |
![]() |
Primakoff effect | production of neutral pseudoscalar mesons by photons interacting with an atomic nucleus |
|
Delbrück scattering | deflection of high-energy photons in the Coulomb field of nuclei |
![]() |
Deep inelastic scattering | a lepton is deflected by a virtual photon emitted by a quark from the hadron |
![]() |
Chiral anomaly | Anomaly-induced neutral pion decay |
![]() |
Flavor-changing neutral current (FCNC) | Hypothetical interactions that change the flavor of a fermion without altering its electric charge, that could happen in the standard model or beyond. |
![]() |
