INITIAL-STATE COLOUR DIPOLE EMISSION ASSOCIATED WITH QCD POMERON EXCHANGE
A. Bialas, R. Peschanski
Abstract
The initial-state radiation of soft colour dipoles produced together with a single QCD Pomeron exchange (BFKL) in onium-onium scattering is calculated in the framework of Mueller's approach. The resulting dipole production grows with increasing energy and reveals an unexpected feature of a power-law tail at appreciably large transverse distances from the collision axis, this phenomenon being related to the scale-invariant structure of dipole-dipole correlations.
