A Pseudoscalar Resonance That Could Resemble the Higgs

As described previously, in SU(5) gauge theory with massless left-handed $ {\bf 5 \oplus 15 \oplus 40 \oplus 45^*}$ fermions \{QUD\}, an S-Matrix is produced by infra-red anomaly dynamics that might provide an extraordinarily economic origin and unification for the Standard Model. All particles are bound-states, with dynamically generated masses, and there is no Higgs sector. In this paper, the radically different dynamical role played by the top quark is elaborated. It does not reproduce Standard Model "$ t\bar{t} $" events but, instead, these events are reproduced by the multiple vector boson decays of the $η_6$ - the remnant pseudoscalar resonance left by color sextet electroweak symmetry breaking. Evidence that the $η_6$ appears in LHC and Tevatron Z pair cross-sections is discussed. A second pseudoscalar resonance, the $η_3$, contains a $t\bar{t}$ pair and mixes with the $η_6$ via the pomeron. The mixing should give the $η_3$ a mass between the triplet and sextet scales. It could also have a decay mode pattern that is more consistent with LHC and Tevatron results than the (mass spectrum determined) pattern of the Standard Model Higgs boson that many hope has been discovered. Unfortunately, at present, there is no possibility to calculate explicit cross-sections.
