A graviton is a term in?
Graviton interaction by gluons, and the weak interaction by the W and Z bosons. All three of these forces appear to be accurately described by the standard model of particle physics. A hypothesis is that gravitational interactions are mediated by an as yet undiscovered elementary particle, dubbed the "graviton". In the classical limit, the theory would reduce to general relativity, which itself reduces to Newton's law of gravitation in the weak-field limit. The term graviton was originally coined in 1934 by Soviet physicists Dmitrii Blokhintsev and F. Gal'perin. When describing graviton interactions, the classical theory of Feynman diagrams, and semiclassical corrections
Graviton Graviton In theories of quantum gravity, the graviton is the hypothetical elementary particle that mediates the force of gravity. There is no complete quantum field theory of gravitons due to an outstanding mathematical problem with renormalization in general relativity. In string theory, believed to be a consistent theory of quantum gravity, the graviton is a massless state of a fundamental string. If it exists, the graviton is expected to be massless because the gravitational force is very long range and appears to propagate at the speed of light. The graviton must be a spin-2 boson because the source of gravitation
