“…Colorons can be produced at the LHC by quark-antiquark fusion at a rate determined by the C coupling to light quarks, g s tan θ. Gluon-gluon fusion production, on the other hand, is forbidden at tree level by SU (3) C gauge invariance [24][25][26], and has been found to be insignificant at the one-loop level [27]. The CMS search for di-jet resonances [2, 3] has considered the hypothesis of a flavor universal coloron, taking this model as a benchmark and fixing tan θ = 1.…”

Anticipating that a di-jet resonance could be discovered at the 14 TeV LHC, we present two different strategies to reveal the nature of such a particle; in particular to discern whether it is a quarkantiquark (qq), quark-gluon (qg), or gluon-gluon (gg) resonance. The first method relies on the color discriminant variable, which can be calculated at the LHC from the measurements of the di-jet signal cross section, the resonance mass and the resonance width. Including estimated statistical uncertainties and experimental resolution, we show that a qg excited quark resonance can be efficiently distinguished from either aqq coloron or a gg color-octet scalar using the color discriminant variable at LHC-14. The second strategy is based on the study of the energy profiles of the two leading jets in the di-jet channel. Including statistical uncertainties in the signal and the QCD backgrounds, we show that one can distinguish, in a model-independent way, between gg, qg, and qq resonances; an evaluation of systematic uncertainties in the measurement of the jet energy profile will require a detailed detector study once sufficient 14 TeV di-jet data is in hand.

“…Recently, it has been demonstrated that there is substantial uncertainty in the theoretical estimate of the ρ T 8 production cross section at the Tevatron and that the cross section may be as much as an order of magnitude lower than the naive vector meson dominance estimate [28]. To establish the range of allowed masses, these limits will need to be redone with a reduced theoretical cross section.…”

“…In order to describe this mixing, we use a generalization of Vector Meson Dominance [4] introduced in [5] and developed in [6]. In this approach we choose a representation where all vector fields transform as gauge fields and they mix through a mass matrix.…”

Motivated by new models of dynamical electroweak symmetry breaking that predict a light composite higgs boson, we build an effective lagrangian which describes the Standard Model (with a light Higgs) and vector resonances. We compute the cross section for the associate production of a higgs and a gauge boson. For some values of model parameters we find that the cross section is significantly enhanced with respect to the Standard Model. This enhancement is similar at the LHC and the Tevatron for the same range of resonance mass.
