2 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 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...
متن کاملParke-Taylor amplitudes in the multi-Regge kinematics*
.-. -_ The Parke-Taylor multigluon amplitudes are examined in the multi-R,egge kinematics, which assumes strong rapidity ordering of the produced gluons, and are used to compute the n-gluon production cross section and the gluon-gluon total cross section. Submitted to Physics Letters B * Work supported by the Department of Energy, contract DE-AC03-76SF00515. In hadron scattering processes with ...
متن کاملRadiative Corrections to Qcd Amplitudes in Quasi - Multi - Regge Kinematics
Radiative corrections to QCD amplitudes in the quasi-multi-Regge kinematics are interesting in particular since the Reggeized form of these amplitudes is used in the derivation of the NLO BFKL. This form is a hypothesis which must be at least carefully checked, if not proved. We calculate the radiative corrections in the one-loop approximation using the s-channel unitarity. Compatibility of the...
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...
