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 gamma-gamma mode of the collider to study the production and the decay of an intermediate mass Higgs boson and its KK excitations.
