2019-12-06T07:44:10Z (GMT) by G.P. Salam
Abstract OEDIPUS is a Monte Carlo simulation program 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 correction... Title of program: OEDIPUS Catalogue Id: ADGK_v1_0 Nature of problem BFKL evolution [1] of a heavy (quark-)onium, to give full information on the rapidity and transverse positions of gluons carrying a small fraction x of the onium's longitudinal momentum. This informaiton can be used to calculate a variety of onium-onium scattering cross sections, including multiple pomeron contributions, which restore unitarity.
