Simulated Beam-Beam Limit for Circular Higgs Factories

We report simulation studies of the beam-beam limit for two proposed circular e+e- Higgs factories with circumference of 27 and 80 km, respectively, called LEP3 and TLEP. In particular we investigate the dependence of the steady-state luminosity and transverse beam sizes on the synchrotron tune (or...

Sumario:We report simulation studies of the beam-beam limit for two proposed circular e+e- Higgs factories with circumference of 27 and 80 km, respectively, called LEP3 and TLEP. In particular we investigate the dependence of the steady-state luminosity and transverse beam sizes on the synchrotron tune (or momentum compaction factor) and on the betatron tunes, as well as the consequences of the strong radiation damping and the implications of the large hourglass effect.
