摘要
We investigate the effects of unparticles on gamma gamma -> gamma gamma scattering for the photon collider mode of the future multi-TeV e(+)e(-) linear collider. We show the effects of unparticles on the differential, and total scattering cross sections for different polarization configurations. Considering 1-loop standard model background contributions from the charged fermions and W-+/- bosons to the cross section, we calculate the upper limits on the unparticle couplings lambda(0) to the photons for various values of the scaling dimension d (1 < d < 2) at root s = 0.5-5 TeV.
