Models with universal extra dimensions predict that each Standard Model particle is accompanied by a tower of Kaluza-Klein resonances. Canonical searches for the production and cascade decays of first Kaluza-Klein modes through missing transverse momentum signatures suffer in general from low detection efficiencies because of the rather compressed Kaluza-Klein particle mass spectrum. Here, we instead analyze signatures from the production of second Kaluza-Klein states which can decay into Standard Model particles and thus do not result in any missing transverse momentum. Such signatures provide a strong sensitivity, and are of particular interest as they would allow for a clear distinction between extra dimensional models and other new physics such as minimal supersymmetric models. We constrain the production of second Kaluza-Xlein particles from recent LAIC searches for dilepton resonances, and place limits on the compactification scale R-1 greater than or similar to 715 GeV and on the masses of the second Kaluza-Klein particles M-KK(2) greater than or similar to 1.4 TeV in the minimal UED model.
