On Unparticle Searches through Photon-Photon Scattering

Abstract

In this work, we study the effects of the spin-0 unparticle on γγ → γγ process. From the numerical results, we show that the cross section with unparticle effect should be about 10 27-10 30 times larger than the one that is confirmed by QED calculation. This could have important implications for unparticle searches and for the measurement of the photon-photon cross section.
