The International Linear Collider as a Kaluza–Klein factory

Abstract

In the minimal Universal Extra Dimension model, single production of n=2 gauge bosons provides a unique discriminating feature from supersymmetry. We discuss how the proposed International Linear Collider can act as a n=2 factory, much in the same vein as LEP. We also touch upon the potential of the γγ mode of the collider to study the production and the decay of an intermediate mass Higgs boson and its KK excitations.
