Associated production of a Kaluza Klein excitation of a gluon with a tt¯ pair at the LHC
Abstract
In certain model-realizations of the Randall-Sundrum scenario, the Kaluza-Klein (KK) excitations of the gluon, gKK have enhanced couplings to right-handed top quarks. In the absence of a gggKK coupling in these models, the single production of a gKK from an initial gg state is not possible. The search for other production mechanisms at the LHC, therefore, becomes important. We suggest that the associated production of a gKK with a ttbar pair is such a mechanism. Our parton-level study, which neglects detection efficiencies, shows that through this process the LHC can probe KK gluon masses in the range of 2.8-3.0 TeV.
