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 missing energy for √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.
