Abstract:
We analyze high energy behaviour of multi-gluon exchange amplitudes in the leading-ln approximation in perturbation theory. Working in the Coulomb gauge and employing Ward identities we derive an integral equation for the -gluon system in the exchange channel. We find that the Regge behaviour is associated with exponentiation of leading infrared divergences, and the position of the -plane singularities is determined by the colour quantum numbers of the exchanged system.- QUANTUM CHROMODYNAMICS
