Two universal extra dimensions and spinless photons at the ILC.
We study the ILC phenomenology of Kaluza-Klein (KK) modes along two universal extra dimensions compactified on the chiral square. We compute production cross sections of various (1, 0) particles at the ILC with (s){sup 1/2} = 1 TeV, focusing on decays of KK-leptons and the KK partner of the hypercharge gauge boson down to the 'spinless photon', which is the lightest KK particle. We contrast this model to one universal extra dimension with KK-photon (spin-1) and supersymmetry with neutralino (spin-1/2) or gravitino (spin-3/2) dark matter. We also investigate the discovery potential for (1, 1) KK bosons as s-channel resonances.
