List_of_Feynman_diagrams Knowpia

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
Box diagram	Photon-photon scattering
Higgs boson production	Via gluons and top quarks
Higgs boson production	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 $\pi ^{0}\to \gamma \gamma ~.$
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.
