List of Feynman diagrams

Short description: List with diagrams of common Feynman diagrams

This is a list of common Feynman diagrams. His first published diagram appeared in Physical Review in 1949.^[1]

Name or phenomenon	Description	Diagram
Beta decay and Free neutron decay	In beta decay, a beta particle is emitted from an atomic nucleus, and the nucleus gains a proton in place of the neutron. In free neutron decay, a neutron not bound to a nucleus (i.e. free) decays with the same process and products.	200px
Compton scattering	scattering of a photon by a charged particle	File:Compton-scattering.svg
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	File:MollerScattering-t.svg
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	File:Tadpole.png
Self-interaction or oyster diagram	An electron emits and reabsorbs a photon	File:Electron self energy.svg
Box diagram	The box diagram for kaon oscillations	200px
Box diagram	Photon-photon scattering	File:Photon-photon scattering.svg
Higgs boson production	Via gluons and top quarks	200px
Higgs boson production	Via quarks and W or Z bosons	200px
Quad cancellations	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
Deep inelastic scattering	a lepton is deflected by a virtual photon emitted by a quark from the hadron	250px
Chiral anomaly	Anomaly-induced neutral pion decay $π^{0} \to γ γ .$	300px
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.	200px
