The Effect of Unparticle in the Processes \(e^{+}e^{-}\rightarrow \gamma \gamma\) and \(\gamma e^{-}\rightarrow U^{\mu }e^{-}\) when the \(e^{+},e^{-}\) Beams Are Polarized in Unparticle Physics

We investigate the influence of unparticle physics on the positron-electron  collider via the scalar unparticle  and electron  exchange. From computing the contribution of the unparticle exchange to the cross-section (CS) as well as evaluating the dependence of differential cross-section (DCS) on the scattering angle , we calculate the production of vector unparticle in the photon-electron  collider in s- and t- channels such as missing energy distribution. Besides, we also found that the polarization of the beams also significantly contributes to the CS and DCS of the unparticle production.
