A. Bialas et R. Peschanski, INITIAL-STATE COLOR DIPOLE EMISSION ASSOCIATED WITH QCD POMERON EXCHANGE, Physics letters. Section B, 355(1-2), 1995, pp. 301-307
The initial-state radiation of soft colour dipoles produced together w
ith a single QCD Pomeron exchange (BFKL) in onium-onium scattering is
calculated in the framework of Mueller's approach. The resulting dipol
e production grows with increasing energy and reveals an unexpected fe
ature of a power-law tail at appreciably large transverse distances fr
om the collision axis, this phenomenon being related to the scale-inva
riant structure of dipole-dipole correlations.
