BBBREM — Monte Carlo simulation of radiative Bhabha scattering in the very forward direction
Description
Abstract A fast and simple Monte Carlo program is presented that simulates single Bremsstrahlung in Bhabha scattering, e^+ e^-→ e^+ e^- γ, without constraints on scattering angles. This allows the study of this process at arbitrarily small, or even vanishing, scattering angles. Experimental cuts can be imposed on an event-by-event basis, allowing for detailed studies of the process as a limitation to beam lifetimes, or a luminosity-measuring device, in e^+ e^-storage rings. As an application, we s... Title of program: BBBREM Catalogue Id: ACTW_v1_0 Nature of problem Radiative Bhabha scattering, e+e- -> e+e-gamma, has a very large cross section at small scattering angles, and plays various roles in existing and future e+e- colliders. It can be an important background to several two-photon scattering processes; it forms the major ingredient in the finite lifetime of colliding beams; and it is a possible process by which the luminosity can be measured, by observing electrons or photons emerging at zero scattering angle. Accurate knowledge of its cross section ...
