Beam-beam simulation studies for PEP-II and KEKB

We have performed 3D PIC simulations for PEP-II, SuperKEKB and KEKB parameters by using SLAC[1], LBL[3] and KEK[2] code. Input parameters for PEP-II, SuperKEKB and KEKB are listed in table 1, 2, 3, respectively. The simulation results are shown in Fig. 1, 2, 3 and 4. These results are in reasonable agreement. For PEP-II parameter at the LER horizontal tune of 0.5125, Luminosity by KEK code is slightly larger than that by SLAC code, which is 8.5 and 7.4 ×1030 /cm/sec, respectively (Fig. 1). Luminosity by LBL and KEK code is almost same and which is 6.1 and 5.7×1030 /cm/sec at the ν x = 0.5253 (Fig. 2), respectively. SLAC-PUB-10301
