  The CMS collaboration has recently conducted a search for trijet resonances
in multi-jet events at the LHC. Motivated in part by this analysis, we examine
the phenomenology of exotic particles transforming under higher representations
of SU(3) color, focusing on those representations which intrinsically prohibit
decays to fewer than three jets. We determine the LHC discovery reach for a
particle transforming in a representation of this sort and discuss several
additional theoretical and phenomenological constraints which apply to such a
particle. Furthermore, we demonstrate that such a particle can provide a
consistent explanation for a trijet excess (an invariant-mass peak of roughly
375 GeV) observed in the recent CMS study.
