Description
In the context of an universal extra-dimensional scenario, we consider
production of the first Kaluza-Klein electron positron pair in an $e^+e^-$
collider as a case-study for the future International Linear Collider. The
Kaluza-Klein electron decays into a nearly degenerate Kaluza-Klein photon and
a standard electron, the former carrying away missing energy. The Kaluza-Klein
electron and photon states are heavy with their masses around the inverse
radius of compactification, and their splitting is controlled by radiative
corrections originating from bulk and brane-localised interactions. We look
for the signal event $e^+e^- +$ large missing energy for $\sqrt s = 1$ TeV and
observe that with a few hundred fb$^{-1}$ luminosity the signal will be
readily detectable over the standard model background. We comment on how this
signal may be distinguished from similar events from other new physics.
