The Triangle Anomaly in the Triple-Regge Limit
The U(1) triangle anomaly is present, as an infra-red divergence, in the
six-reggeon triple-regge interaction vertex obtained from a maximally
non-planar Feynman diagram in the full triple-regge limit of three-to-three
quark scattering.Comment: 7 pages, with 5 PS figures in the text. Talk presented at the XXIX

Could a Weak Coupling Massless SU(5) Theory Underly the Standard Model S-Matrix?
The unitary Critical Pomeron connects to a unique massless left-handed SU(5)
theory that, remarkably, might provide an unconventional underlying unification
for the Standard Model. Multi-regge theory suggests the existence of a {\it
bound-state high-energy S-Matrix} that replicates Standard Model states and
interactions via massless fermion anomaly dynamics. Configurations of anomalous
wee gauge boson reggeons play a vacuum-like role. All particles, including
neutrinos, are bound-states with dynamical masses (there is no Higgs field)
that are formed (in part) by anomaly poles. The contributing zero-momentum
chirality transitions break the SU(5) symmetry to vector SU(3)xU(1) in the
S-Matrix. The high-energy interactions are vector reggeon exchanges accompanied
by wee boson sums (odd-signature for the strong interaction and even-signature
for the electroweak interaction) that strongly enhance couplings. The very
small SU(5) coupling, ~ 1/120, should be reflected in small (Majorana) neutrino
masses. A color sextet quark sector, still to be discovered, produces both Dark
Matter and Electroweak Symmetry Breaking. Anomaly color factors imply this
sector could be produced at the LHC with large cross-sections, and would be
definitively identified in double pomeron processes.Comment: Contributed to the Proceedings of the Gribov-80 Memorial Workshop

Past, Present, and Future Multi-Regge Theory
The connection of the unitary Critical Pomeron to QUD - a unique massless,
infra-red fixed-point, left-handed SU(5) field theory that might provide an
unconventional underlying unification for the Standard Model, is discussed in
the context of developments in past, present, and future multi-regge theory.
The QUD bound-state S-Matrix is accessible via elaborate (non-planar)
multi-regge theory. Standard Model states and interactions are replicated via
massless fermion anomaly dynamics in which configurations of infra-red
divergent anomalous gauge boson reggeons play a wee parton vacuum-like role.
All particles, including neutrinos, are bound-states with dynamical masses and
there is no Higgs field.
A color sextet quark sector, that could be discovered at the LHC, produces
both Dark Matter and Electroweak Symmetry Breaking and the very small QUD
coupling should be reflected in the smallness of neutrino masses.
The origin of the Standard Model could be that it is reproducing the unique,
unitary, S-Matrix
