High-Energy Unitarity and the Standard Model
High-energy unitarity is argued to select a special version of QCD as the
strong interaction. Electroweak symmetry breaking has to be due to a new sextet
quark sector - that will produce large cross-section effects at the LHC. The
sextet sector embeds, uniquely, in a massless SU(5) theory that potentially
generates the states and interactions of the Standard Model within a
bound-state S-Matrix. Infra-red chirality transitions of the massless Dirac sea
play an essential dynamical role.Comment: Contributed to the Proceedings of the Gribov-75 Memorial Worksho
AMS-02, Strongly Self-Interacting Dark Matter, and QUD
The latest AMS-02 electron/positron precision data add to the spectrum knee
as direct cosmic ray evidence for an electroweak scale strong interaction. In
addition, there is significant evidence for a strong self-interaction of dark
matter. QUD is a unique massless SU(5) field theory with an anomaly-generated
bound-state S-Matrix that could be an unconventional origin for the Standard
Model. The electroweak scale color sextet quark enhanced QCD interaction is the
only new physics. Production of multiple vector bosons, that acquire masses via
sextet quark pions, will give the AMS positron and electron cross-sections -
related vector boson pair production having been seen at the LHC. Stable sextet
quark neutrons (neusons) provide a novel form of very strongly interacting dark
matter that has the desired experimental properties. Large rapidity hadronic
production of neusons will produce the knee
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
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

Application of distorted models in developing scaled structural models
In the design and development of dynamically similar structural models a distorted model of the panel is used. The panel thickness is made larger than that dictated by geometric scaling, and the mass of the panel is decreased by adding mass to the surface of the panel to counteract the additional stiffness obtained by the thickness increase
