Dipole description of inclusive particle production

The effects of multiple interactions in colliding particles (e.g. in nucleus–nucleus collisions) are modelled using the light-cone dipole approach. Guided by the Abelian analogue of multi-photon interactions in the production of a pair of charged particles, we relate the inclusive cross section of quark pair production with the cross sections of the interaction of a QCD dipole with either the beam or the target.
