In theoretical physics, a graviphoton is a hypothetical particle that emerges as an excitation of the metric tensor (i.e. gravitational field) but whose physical properties are virtually indistinguishable from a photon, as shown in Kaluza-Klein theory. The electromagnetic potential Aμ comes from a component of the metric tensor gμ5 where the figure 5 labels an additional, fifth dimension. In theories with extended supersymmetry, a graviphoton is usually a superpartner of the graviton that behaves as a photon. See also * graviscalar Retrieved from "http://en.wikipedia.org/" |
