An attempt is made to present the contribution of the scalar unparticle on the Z-production cross-section at International Linear Colliders (ILC) with polarized initial beams in the Randall-Sundrum model. The cross-sections depend strongly on the polarization of $e^{-}$, $e^{+}$ initial beams, the center of mass energy $\sqrt{s} $, the scaling dimension $d_{U}$ of the unparticle operator $\mathcal{O}_{U}$ and the energy scale $\Lambda_{U}$. The results indicate that with the effect of the scalar propagators in the s-channel, including radion, Higgs and scalar unparticle, the cross-section for the ZZ production is enhanced and larger than that in the Standard model under the same conditions. |
