List of Feynman diagrams

This is a list of common Feynman diagrams.

Name or phenomenon Description Diagram
Beta decay
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 creation and annihilation In the Stückelberg–Feynman interpretation, pair annihilation is the same process as pair creation
Penguin diagram
Box diagram The box diagram for kaon oscillations
Higgs boson production Via gluons and top quarks
Via quarks and W or Z bosons
One of the many cancellations to the quadratic divergence to squared mass of the Higgs boson which occurs in the MSSM.
Primakoff effect
