Abstract :
We have studied the parasitic long-range beam-beam effect at the KEKB by a strong-strong beam-beam simulation. Simulation result shows a parasitic long-range non-linear beam-beam effect change the contour diagram of the luminosity. The luminosity degradation is observed near the half integer tune due to the dynamic beta effect.
