Phenomenology of the Renormalizable Coloron Model

The renormalizable coloron model constitutes the minimal extension of the standard model (SM) color sector to $SU(3)_{1c} \times SU(3)_{2c}$, with the spontaneous symmetry breaking of the extended gauge group to the diagonal QCD facilitated by the renormalizable operators. It predicts the existence of the beyond the SM massive color-octet gauge bosons (colorons), colored and uncolored scalar degrees of freedom, as well as potential spectator fermions necessary for anomaly-cancelation purposes. Furthermore, keeping the ordinary chiral quark charge assignments under the extended color gauge group in their most general form, the framework (effectively) captures a large class of models available within the literature. This contribution summarizes the current formal and phenomenological constraints on the free parameter space of the theory, as well as the LHC $\sqrt s = 14$ TeV prospects for discovering its heavy scalar. The model is well-constrained and highly predictive; in particular, it is shown that the parameter space can be thoroughly probed by the LHC and the next generation hadron colliders, making it a promising beyond the SM candidate for exploration. In addition, the significance of the NLO corrections to the coloron production cross section are discussed.
