Solving Qcd Using Multi - Regge Theory ∗
This talk outlines the derivation of a high-energy, transverse momentum cutoff , 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 colo...
متن کاملRegge Theory and Multi–Reggeon Exchange
We analyze conformal field theory 4–point functions of the form A ∼ 〈O1 (x1)O2 (x2)O1 (x3)O2 (x4)〉, where the operators Oi are scalar primaries. We show that, in the Lorentzian regime, the limit x1 → x3 is dominated by the exchange of conformal partial waves of highest spin. When partial waves of arbitrary spin contribute to A, the behavior of the Lorentzian amplitude for x1 → x3 must be analyz...
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 کامل2 Multi - Regge form of QCD amplitudes
The multi–Regge form of QCD amplitudes with gluon exchanges is proved in the next-to-leading approximation. The proof is based on the bootstrap relations, which are required for the compatibility of this form with the s-channel unitarity. We show that the fulfillment of all these relations ensures the Reggeized form of energy dependent radiative corrections order by order in perturbation theory...
متن کاملDimensional perturbation theory for Regge poles
We apply dimensional perturbation theory to the calculation of Regge pole positions, providing a systematic improvement to earlier analytic first-order results. We consider the orbital angular momentum l as a function of spatial dimension D for a given energy E , and expand l in inverse powers of k[(D21)/2. It is demonstrated for both bound and resonance states that the resulting perturbation s...
