Confinement and 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 paper derives a high-energy, transverse momentum cutoff, confining solution of QCD. The Pomeron, in a first approximation, is a single Reggeized gluon plus a {open_quotes}wee-parton{close_quotes} component that compensates for the color and particle properties of the gluon. This solution corresponds to a supercritical phase of Reggeon field theory. Beginning with the multi-Regge behavior of massive quark and gluon amplitudes, Reggeon unitarity is used to derive a Reggeon diagram description of a wide class of multi-Regge amplitudes, including those describing the formation and scattering of bound-state Regge poles. When quark and gluon masses are taken to zero, a logarithmic divergence is produced by helicity-flip Reggeon interactions containing the infrared quark triangle anomaly. With the gauge symmetry partially broken, this divergence selects the bound states and amplitudes of a confining theory. Both the Pomeron and hadrons have an anomalous color-parity wee-parton component. For the Pomeron the wee-parton component determines that it carries negative color charge parity and that the leading singularity is an isolated Regge pole. {copyright} {ital 1998} {ital The American Physical Society}
