The Anomaly and Reggeon Field Theory in Qcd
نویسنده
چکیده
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.

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 highenergy, transverse momentum cut-off, confining solution of QCD. The pomeron, in first approximation, is a single reggeized gluon plus a “wee parton” component that compen...
متن کاملAnalytic Multi - Regge Theory and the Pomeron in Qcd : Ii . Gauge Theory
The high-energy Regge behavior of gauge theories is studied via the formalism of Analytic Multi-Regge Theory. Perturbative results for spontaneously-broken theories are first organised into reggeon diagrams. Unbroken gauge theories are studied via a reggeon diagram infra-red analysis of symmetry restoration. Massless fermions play a crucial role and the case of QCD involves the Super-Critical P...
متن کاملChirality Violation in Qcd Reggeon Interactions
The appearance of the triangle graph infra-red axial anomaly in reduced quark loops contributing to QCD triple-regge interactions is studied. In a dispersion relation formalism, the anomaly can only be present in the contributions of unphysical triple discontinuities. In this paper an asymptotic discontinuity analysis is applied to high-order feynman diagrams to show that the anomaly does indee...
متن کاملChirality 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 multireggeon 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 ...
متن کاملRegge amplitudes from AdS/CFT duality
It is well-known that string theory started from the proposal of scattering amplitudes which may grasp the two major structures of soft interaction phenomenology in a condensed form : resonances and Regge poles. Two types of amplitudes were proposed for four-point amplitudes, see Fig.1. The Veneziano amplitude corresponds to Reggeon exchanges with non-vacuum quantum numbers and the Shapiro-Vira...
