Standard model gauge bosons propagating in two universal extra dimensions give rise to heavy spin-1 and spin-0 particles. The lightest of these, carrying Kaluza-Klein numbers (1,0), may be produced only in pairs at colliders, whereas the (1,1) modes, which are heavier by a factor of {radical}(2), may be singly produced. We show that the cascade decays of (1,1) particles generate a series of closely-spaced narrow resonances in the tt invariant mass distribution. At the Tevatron, s-channel… Expand
