Universal Extra Dimensions and Kaluza-Klein Bound States
arXiv:hep-ph/0409024
Abstract
We study the bounds states of the Kaluza-Klein (KK) excitations of quarks in models of Universal Extra Dimensions. Such bound states may be detected at future lepton colliders in the cross section for the pair-production of KK-quarks near threshold. For typical values of model parameters, we find the ``KK-quarkonia'' have widths in the 10-100 MeV range, and production cross sections of order a few picobarns for the lightest resonances. Two body decays of the constituent KK-quarks lead to distinctive experimental signatures.
