• # Abstract

We consider the UED scenario and study the detectability of the first KK electron-positron pair at the ILC. A few hundred GeV KK electron decays into a nearly degenerate KK photon, which carries away missing energy, and the standard electron. The mass splitting between the KK electron and KK photon is controlled by the bulk- and brane-induced radiative corrections. We look for the signal event $e^{+} e^{-} +$ large missingenergy for $\sqrt{s} = 1$ TeV and observe that with a few hundred fb-1 luminosity the signal can be deciphered from the standard model background. We briefly outline how the UED signals may be distinguished from the supersymmetric signals.
