The Feynman diagrams are much easier to keep track of than "old-fashioned" terms, because the old-fashioned way treats the particle and antiparticle contributions as separate. Each Feynman diagram is the sum of exponentially many old-fashioned terms, because each internal line can separately represent either a particle or an antiparticle.
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 ...
Fig. 1: Schematic diagram of Compton's experiment. Compton scattering occurs in the graphite target on the left. The slit passes X-ray photons scattered at the selected angle and their average energy rate is measured using Bragg scattering from the crystal on the right in conjunction with an ionization chamber.
Incidentally, the name given to this process of a photon interacting with an electron in this way is Compton scattering. [citation needed] There is an infinite number of other intermediate "virtual" processes in which more and more photons are absorbed and/or emitted. For each of these processes, a Feynman diagram could be drawn describing it.
A Feynman diagram (box diagram) for photon–photon scattering: one photon scatters from the transient vacuum charge fluctuations of the other. Two-photon physics, also called gamma–gamma physics, is a branch of particle physics that describes the interactions between two photons. Normally, beams of light pass through each other unperturbed.
Feynman diagram of electron–positron pair production. One must calculate multiple diagrams to get the net cross section. The exact analytic form for the cross section of pair production must be calculated through quantum electrodynamics in the form of Feynman diagrams and results in a complicated function. To simplify, the cross section can ...
Compton Scattering Feynman Diagram Main article: Compton scattering Compton scattering , so named for Arthur Compton who first observed the effect in 1922 and which earned him the 1927 Nobel Prize in Physics; [ 25 ] is the inelastic scattering of a high-energy photon by a free charged particle.
In quantum electrodynamics, Bhabha scattering is the electron-positron scattering process: e + e − → e + e − {\displaystyle e^{+}e^{-}\rightarrow e^{+}e^{-}} There are two leading-order Feynman diagrams contributing to this interaction: an annihilation process and a scattering process.
