Feynman Diagrams are used to represent the fundamental forces by which elementary particles interact. In all interactions, time flows horizontally to the right.

a)  Quantum Electrodynamics:  An electron converts into an electron, with the emission of a photon (e → e + γ)

b)  Quantum Chromodynamics: A quark converts into a quark, with the emission of a gluon (q → q + g)

c)  Neutral Weak Interactions: Any lepton or quark converts into the corresponding lepton or quark, with the emission of a Z boson (f → f + Z)

d)  Charged Weak Interactions for Leptons: A negative lepton converts into a corresponding neutrino, with the emission of a W- boson (l- → νl + W-)

e)  Charged Weak Interactions for Quarks: A quark with charge -1/3 converts into the corresponding quark with charge +2/3, with the emission of a W- boson (q-1/3 → q+2/3 + W-)
