Abstract
We investigate the effects of unparticles on Compton scattering, eγ→eγ based on a future e+e- linear collider such as the CLIC. For different polarization configurations, we calculate the upper limits on the unparticle coupling λ0 for a discovery reach at the center-of-mass energies 
–3.0 TeV. Our results for the upper limits on λ0 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 λ0 get stronger as the collider energy and/or the luminosity increase.
