Deep-Inelastic Diffraction and the Pomeron as a Single Gluon
Deep-inelastic diffractive scaling provides fundamental insight into the QCD
pomeron. It is argued that single gluon domination of the structure function,
together with the well-known Regge pole property, determines that the pomeron
carries color-charge parity $ C_c = -1~$ and, at short distances, is in a
super-critical phase of Reggeon Field Theory. The main purpose of the talk is
to describe the relationship of the super-critical pomeron to QCD.

The Supercritical Pomeron in QCD
Deep-inelastic diffractive scaling violations have provided fundamental
insight into the QCD pomeron, suggesting a single gluon inner structure rather
than that of a perturbative two-gluon bound state. This talk outlines a
derivation of a high-energy, transverse momentum cut-off, confining solution of
QCD. The pomeron, in first approximation, is a single reggeized gluon plus a
``wee parton'' component that compensates for the color and particle properties
of the gluon. This solution corresponds to a supercritical phase of Reggeon
Field Theory.

Solving QCD Using Multi-Regge Theory
This talk outlines the derivation of a high-energy, transverse momentum
cut-off, solution of QCD in which the Regge pole and ``single gluon''
properties of the pomeron are directly related to the confinement and chiral
symmetry breaking properties of the hadron spectrum. In first approximation,
the pomeron is a single reggeized gluon plus a ``wee parton'' component that
compensates for the color and particle properties of the gluon. This solution
corresponds to a supercritical phase of Reggeon Field Theory.

Solving QCD Via Multi-Regge Theory
A high-energy, transverse momentum cut-off, solution of QCD is outlined.
Regge pole and ``single gluon'' properties of the pomeron are directly related
to the confinement and chiral symmetry breaking properties of the hadron
spectrum. This solution, which corresponds to a supercritical phase of Reggeon
Field Theory, may only be applicable to QCD with a very special quark content.

The Triple-Regge Triangle Anomaly
It is shown that the 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. A multi-regge asymptotic dispersion relation formalism can be
used to isolate all anomaly contributions and to discuss when and how there is
a cancelation.

The Anomaly and Reggeon Field Theory in QCD
The appearance of the U(1) anomaly in the interactions of reggeized gluons is
described. Also discussed is the crucial role the anomaly can play in providing
the non-perturbative properties necessary for a transition from gluon and quark
reggeon diagrams to hadron reggeons and a reggeon field theory description of
the pomeron.

Chirality Violation in the QCD High-Energy S-Matrix
In a previous paper it has been shown that the infra-red divergence
associated with the triangle graph axial anomaly can occur in triple-regge
multi-reggeon interactions due to unphysical asymptotic triple discontinuities.
In this paper an asymptotic discontinuity analysis is applied to high-order
feynman diagrams to show that the anomaly exists in contributions to the
triple-regge nine-reggeon interaction. This implies that the anomaly occurs in
the interactions of reggeon states that have the quantum numbers of the anomaly
current and establishes a direct connection with the well-known U(1) problem.

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.

Sextet Quarks and the Pomeron at the LHC
Adding two color sextet quarks to QCD gives many special features. The
high-energy S-Matrix, constructed via reggeon diagrams and chiral anomalies,
contains the Critical Pomeron and electroweak symmetry breaking is produced, by
sextet pions. Cosmic ray phenomena suggest large cross-section effects will be
seen at the LHC, in particular, involving the pomeron. The sextet sector
embeds, uniquely, in a massless, confining, left-handed SU(5) theory. The
anomaly based high-energy S-Matrix could be that of the full Standard Model.

The Gribov Legacy, Gauge Theories and the Physical S-Matrix
Reggeon unitarity and non-abelian gauge field copies are focussed on as two
Gribov discoveries that, it is suggested, may ultimately be seen as the most
significant and that could, in the far distant future, form the cornerstones of
his legacy. The crucial role played by the Gribov ambiguity in the construction
of gauge theory bound-state amplitudes via reggeon unitarity is described. It
is suggested that the existence of a physical, unitary, S-Matrix in a gauge
theory is a major requirement that could even determine the theory.
