A theoretical attempt is made to present the contribution of the unparticles to the two well-known processes Bhabha and Møller scattering. We concentrate on the lepton processes: μ ± + μ − → μ ± + μ − in Randall-Sundrum mode under the influence of the unparticles. We evaluate differential cross-sections versus the scattering angle θ, total cross-sections versus the scaling dimension dU and the center-of-mass energy √ s. The reach of energy chosen corresponds to the energy region at CMS. The processes are studied when the incoming and outgoing beams of particles are unpolarized and polarized. We also calculated the number of events, based on the luminosity of the colliders at present or in projection in the future in the previous articles. The numerical results show that as unparticles contribute to all the studied processes, the total cross-sections increase at the high energy with the small scaling dimension. The results subsequently lead to the relevance between theories and experiments in the near future as for the total cross-section in the processes we restricted.
