  The existence of colour-octet scalar states, often dubbed sgluons, is
predicted in many extensions of the Standard Model of particle physics, such as
supersymmetric realisations featuring Dirac gauginos. Such states have a large
pair-production rate at hadron colliders and mainly decay into pairs of jets
and top quarks. Consequently, they represent a primary target for experimental
searches for new resonances in the multijet and multitop channels at the Large
Hadron Collider. Adopting a phenomenologically-motivated simplified model, we
reinterpret the results of a recent experimental search for the four-top-quark
Standard Model signal, from which we constrain the sgluon mass to be larger
than about 1.06 TeV. We additionally consider how modifications of the existing
four-top-quark studies could enhance our ability to unravel the presence of
scalar octets in data.
