OEDIPUS: Onium Evolution, Dipole Interaction and Perturbative Unitarisation Simulation
Abstract
A Monte Carlo simulation program is presented which can be used to determine the small-x evolution of a heavy onium using Mueller's colour dipole formulation, giving the full distribution of dipoles in rapidity and impact parameter. Routines are also provided which calculate onium-onium scattering amplitudes between individual pairs of onium configurations, making it possible to establish the contribution of multiple pomeron exchange terms to onium-onium scattering (the unitarisation corrections).
