In the particle picture, the interactions can be conveniently described by Feynman diagrams, which may be regarded either as branch diagrams of the perturbation expansion or as collision diagrams. The derivation of the transfer expressions can then be reduced to a few general rules for the ...
weak and strong interactions; gravitation is excluded—provides us with an impressive comprehensive framework for understanding the behavior of the constituents of all visible matter, as well as all the unstable elementary particles that have been discovered...

(1951–88), where he continued to apply his quantum electrodynamic theories to the "superfluidity" of liquid helium. With colleague Gell-Mann, he developed the Conserved Vector Current hypothesis of weak subatomic particle interactions (1958). Feynman shared the 1965 Nobel Prize with Schwinger and...
The so-called strong interaction, the meson-baryon interaction, has a strength of 1 in this scale, and the law is completely unknown, although there are a number of known rules, such as that the number of baryons does not change in any reaction. Table 2-3. Elementary Interactions This ...
(for interactions propor- tional to the electromagnetic coupling e, and therefore the weak coupling g = e/sW with sW being the sine of the electroweak mixing angle, or any of the model's Yukawa or supersymmetry-breaking multiscalar interactions) and QCD (for QCD interactions). These tags are...
We must limit ourselves to the more basic question of the rules of the game.If we know the rules, we consider that we “understand” the world. — Richard P. Feynman In 'Basic Physics', The Feynman Lectures on Physics (1964, 2013), Vol. 1, 2-1. ...

A diagram used in quantum electrodynamics and quantum chromodynamics to help describe and visualize the possible interactions between particles. Fermions are represented with straight lines, and bosons...
As a partial test of a recently proposed theory, based on N -body linear integral equations and self-consistency ideas, we examine the weak-coupling limit and show that the Feynman-Dyston rules can be derived. Since the integral equations are not solved exactly, but rather by iteration, the...
We will also comment in this section on the reasons of breakdown of conformality by double-trace interactions in these χFTs and of the persistence of conformal properties of large majority of correlators. 2.1 χFT4 as DS limit of N = 4 SYM The γ-deformed action of N = 4 SYM is ...
