Elastic Photon-Photon Scattering through Four-Wave Coupling
According to the theory of quantum electrodynamics, photon-photon scattering can take place via exchange of virtual electron-positron pairs. Effectively, the interaction can be formulated in terms of non-linear corrections to Maxwell’s equations, and hence may be treated by classical non-linear electrodynamics. Due to the strong electromagnetic fields needed to reach any noticeable effect, phot...
متن کاملUnparticle physics at the photon collider
Recently, a conceptually new physics beyond the Standard Model (SM), unparticle, has been proposed, where a hidden conformal sector is coupled to the SM sector through higher dimensional operators. In this setup, we investigate unparticle physics at the photon collider, in particular, unparticle effects on the γγ → γγ process. Since this process occurs at loop level in the SM, the unparticle ef...
متن کاملUnparticle Physics on Cosmic Ray Photon and E
We study the effects of unparticle physics on the cosmic ray photon and e, including on the pair production (PP) and elastic scattering (ES) of cosmic ray photon off various background radiations, and on the inverse Compton scattering of cosmic ray e with cosmic radiations. We compute the spin-averaged amplitudes squared of three processes and find that the advent of unparticle will never signi...
متن کاملSingle Photon Searches at PEP
The MAC and ASP searches for events with a single photon and no other observed particles are reviewed. New results on the number of neutrino generations and limits on selectron, photino, squark and gluino masses from the ASP experiment are presented. Presented at the SLAC Summer Institute on Particle Physics Stanford, California, July 29 August 9, 1985 * Work supported by the Department of Ener...
متن کاملHadronic photon-photon scattering at LEP
Hadronic interactions of two quasi-real photons have been studied extensively both during the LEP1 and the LEP2 data taking periods. The higher energies available at LEP2 in particular opened regions of phase space where hadronic processes can be predicted reliably by perturbative QCD calculations, usually available to next-to-leading order in the strong coupling constant for the process concer...
