“…6 The RCM was proposed in [26] and has also been studied extensively in [25,[27][28][29][30][31][32]. Unfortunately, we can see from the figure that the RCM would provide an ζ value five orders of magnitude too small.…”

Abstract. If an excess potentially heralding new physics is noticed in collider data, it would be useful to be able to compare the data with entire classes of models at once. This talk discusses a method that applies when the new physics corresponds to the production and decay of a single, relatively narrow, s-channel resonance. A simplifed model of the resonance allows us to convert an estimated signal cross section into model-independent bounds on the product of the branching ratios corresponding to production and decay. This quickly reveals whether a given class of models could possibly produce a signal of the observed size. We will describe how to apply our analysis framework to cases of current experimental interest, including resonances decaying to dibosons, diphotons, dileptons, or dijets.

“…(2.5)), as well as imposing the unitarity condition by performing a full coupled-channel analysis of the two-body scalar scatterings. These analyses have been presented in detail in [1]. Furthermore, a thorough study of the vacuum stability and triviality of the model has been performed in [3], and the viable regions of the parameter space are identified by imposing the conditions (2.5) on the running couplings and, at the same time, requiring the absence of any Landau poles up to a cutoff energy of 100 TeV.…”

“…In case the spontaneous symmetry breaking in the extended color sector occurs within a renormalizable framework [1,7,14], additional colored and uncolored (pseudo-)scalars are predicted within the reach of the LHC. Furthermore, in a formalism where the couplings of the ordinary leftand right-handed quarks to colorons are different (chiral color), potential gauge anomalies may arise, the cancellation of which requires the existence of new chiral spectator fermions with the opposite couplings to colorons as compared with those of the chiral quarks.…”

“…A spontaneous breaking of this extended color gauge group to its diagonal subgroup SU(3) c (identified as the ordinary QCD containing the usual massless gluons) produces the colorons as a massive copy of the gluon color-octet set, 1 but potentially with chiral couplings to quarks. Various types of models (effectively) containing such an extended color gauge group are present within the literature, including: topcolor [6], the flavor-universal coloron [7], chiral color (the axigluon) [8], chiral color with unequal gauge couplings [9], flavor non-universal chiral color [10], flavorful top-coloron model [11], technicolor models with colored technifermions [12], and extra-dimensional models with KK gluons [13].…”

The renormalizable coloron model constitutes the minimal extension of the standard model (SM) color sector to SU(3) 1c × 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 anomalycancelation 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 √ 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.

I study supersymmetric models in which the QCD gauge group is the remnant diagonal subgroup from the spontaneous breaking of an SU (3) × SU (3) gauge group at a multi-TeV scale. In renormalizable models with soft supersymmetry breaking, the scalar potential is shown to have global minima with the required gauge symmetry breaking pattern. In addition to a massive color octet vector boson, this framework predicts 3 color octet spin-0 sgluons, and 4 color octet gluinos with both Dirac and Majorana mass terms. One of the gluino mass eigenstates typically has a coupling to quark-squark pairs that is at least as large as the prediction of minimal supersymmetry, but it need not be the lightest one.
