Beam-beam effects in a collider with a large number of bunches

Description
The understanding and control of the Beam-Beam Interactions (BBIs) in
particle colliders is fundamental to preserve beam stability and achieve
the optimum collider performance.
In the case of the Large Hadron Collider (LHC) at CERN, these forces are experienced as localized periodic distortions when the two beams cross each other in the four experimental areas.
The very large number of bunches in the LHC introduce new effects and their study becomes a challenging task.
The incoherent and coherent beam-beam effects for the LHC have been addressed in a fully self consistent treatment. Complementary numerical and analytical tools have been developed to predict bunch to bunch effects and the objectives are a better understanding of these effects and to provide fast numerical tools to interpret the observations of single bunch measurements during the operation of the collider and to improve its performance. The numerical predictability of bunch to bunch differences has been demonstrated and the predictions have been compared with experimental data from the Relativistic Heavy Ion Collider (RHIC).
