Single top quark production through unparticles at photon colliders

Abstract

We investigate the single top quark production with the exchange of unparticles through high energy photon-photon collision $\gamma \gamma \to t\bar{c}$. The effects of unparticles on the scattering cross sections for different polarization configurations, and for various values of the scaling dimension $d,1<d<2$ are analysed. It is shown that the $(+-)$ polarisation configuration is more preferable searching for unparticle physics signatures.
