Unparticle searches through Compton scattering

We investigate the effects of unparticles on Compton scattering, e.. e. based on a future e(+) e(-) linear collider such as the CLIC. For different polarization con. gurations, we calculate the upper limits on the unparticle coupling lambda(0) for a discovery reach at the center-of-mass energies root s = 0.5 TeV-3.0 TeV. Our results for the upper limits on lambda(0) for the different values of d are comparable with the limits found in the collider physics literature of the unparticle stuff. We show that the limits on lambda(0) get stronger as the collider energy and/or the luminosity increase. Copyright (c) EPLA, 2008.
