Regge Poles in Qcd
Basic properties of Regge poles are reviewed. Regge poles are considered from both t-channel and s-channel points of view. The main part of the review is devoted to the Regge poles in QCD. The method of the Wilson-loop path integral is used to calculate trajectories of Regge poles for q − q̄ and gluonic states. The problem of the Pomeron in QCD is discussed in details. It is shown how to use the...
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...
متن کاملExperimental Consequences of the Hypothesis of Regge Poles
In the nonrelativistic case of the Schrodinger equation, composite particles correspond to Regge poles in scattering amplitudes {poles in the complex plane of angular momentum). It has been suggested that the same may be true in relativistic theory. In that case, the scattering amplitude in which such a particle is exchanged behaves at high energies like s~~'& Lsinvo (t) 7 ', where s is the ene...
متن کاملQuantized tension: Stringy amplitudes with Regge poles and parton behavior
We propose stringy hadronic amplitudes that combine some of the features of sister trajectories and running tension. By summing over string amplitudes with varying Regge trajectories that have integer tension and converging intercept, we obtain parton hard-scattering and Regge soft-scattering behaviors, while preserving discrete poles in both momentum and angular momentum. PACS : 11.25.Pm, 11.2...
متن کاملRegge trajectories of ordinary and non-ordinary mesons from their scattering poles
Our results on obtaining the Regge trajectory of a resonance from its pole in a scattering process and from analytic constraints in the complex angular momentum plane are presented. The method, suited for resonances that dominate an elastic scattering amplitude, has been applied to the ρ(770), f2(1270), f2(1525) and f0(500) resonances. Whereas for the first three we obtain linear Regge trajecto...
