Kaluza-Klein/$Z^{\prime }$ Differentiation at the LHC and Linear Collider

Abstract

We explore the capabilities of the LHC and the Linear Collider(LC) to distinguish the production of Kaluza-Klein(KK) excitations from an ordinary $Z^{\prime }$ within the context of theories with TeV scale extra dimensions. At the LHC, these states are directly produced in the Drell-Yan channel while at the LC the effects of their exchanges are indirectly felt as new contact interactions in processes such as $e^{+}{e}^{-}\to f\bar{f}$. While we demonstrate that the LC is somewhat more capable at KK/$Z^{\prime }$ differentiation than is the LHC, the simplest LC analysis relies upon the LHC data for the resonance mass as an important necessary input.
