  The bound-state S-Matrix of QUD (SU(5) gauge theory with massless left-handed
5 + 15 + 40 + 45* fermions) might underly the success of the Standard Model.
The dynamical role of the QUD top quark leads to two Higgs-like scalar
resonances, the eta_6 - which reproduces Standard Model top events, and the
eta_3 - which could have a mass ~ 125 GeV. The participation of the weak
interaction in the dynamics implies the resonances are not parity eigenstates
and so should have pseudoscalar and scalar electroweak couplings. Also, a
tree-unitarity condition could hold - in part because of the closeness of the
electroweak physical amplitudes to perturbation theory, and - in part because
of the intimate relation with regge behavior. This would imply that the
combined physical couplings of the two resonances are comparable to those of
the Standard Model Higgs boson. Unlike the isolated Standard Model, the
underlying unification of QUD implies there will be no LHC "nightmare scenario"
and that, instead, a broad, extensive, experimental program should, eventually,
be implemented.
