Description
Many theories beyond the Standard Model predict the existence of colored scalar states,
known as sgluons. Sgluons are expected to be copiously pair-produced
at the LHC via strong interactions. In scenarios where they are top-philic, such as SUSY
with Dirac gauginos, sgluons can be sought in multitop events at the LHC. We revisit two LHC Run I analyses
that utilise events with either the same-sign dileptonic or single leptonic decay of a four-top-quark system.
Employing both parameterisations of the detector response and a novel Matrix-Element method,
reinterpretation of these two analyses are performed in the context of sgluon production.
Adopting a simplified model approach, this reinterpretation allows us to extract bounds on the
sgluon mass, and for the first time in the field, its couplings.
