Study of Beam-Beam Interactions with or Without Crossing Angle
ABSTRACT
In recent high luminosity colliders, the finite crossing angle scheme becomes popular to gain the multiplicity of luminosity
with multi-bunch or long bunch operation. Success of KEKB showed that the finite crossing angle scheme was no problem
to achieve the beam-beam parameter up to 0.05. The authors have studied the beam-beam interactions with/without crossing
angle toward higher luminosity. They discuss how the crossing angle affects the beam-beam parameter and luminosity in the
present KEK B factory (KEKB) using computer simulations.
