Description
Gravitons are hypothetical particles that have yet to be directly observed, but they are predicted by various theories, including quantum gravity. One quantum mechanical process that allows for the production of particles that couple to photons, such as gravitons, is light-by-light scattering. While rare, this process can be observed and is sensitive to potential new physics beyond the Standard Model. The limits on the graviton-photon coupling have been set for masses of the graviton ranging from 100 MeV up to 2 TeV at the LHC, assuming a 100% branching ratio to photon pairs and with universal coupling. These limits have been extended to include also electron-positron colliders such as BelleII, BESIII and LEP.
