LHC limits on KK-parity non-conservation in the strong sector of universal extra-dimension models
Abstract
In five-dimensional universal extra-dimensional models compactified on an S1/Z2 orbifold four-dimensional kinetic terms are allowed at the two fixed points. If these terms are unequal then Kaluza-Klein (KK) parity is broken. Within such a framework we consider resonant production of the n = 1 KK-gluon at the Large Hadron Collider and its subsequent decay to tt, where both production and decay are KK-parity non-conserving. We use, for the first time, the exclusion data for a tt resonance obtained by the ATLAS collaboration to limit the mass ranges of quark and gluon excitations of the KK-parity-violating model which are found to be in the ballpark of 900 GeV.
