OEDIPUS: Onium Evolution, Dipole Interaction and Perturbative Unitarisation Simulation Original Research Article

OEDIPUS is a Monte Carlo simulation program which can be used to determine the small-x evolution of a heavy onium using Muellerʹs 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).
