Abstract:

If calculated in the standard way, the cross section for the collision of two unstable particles turns out to diverge. This is because part of such a cross section is proportional to the size of the colliding beams. This effect is called the "linear beam size effect". We present a way of including this linear beam size effect in the usual Monte Carlo integration procedure. Furthermore we discuss the gauge breaking that this may cause.
