A Feasibility Study of an e+e- Ring Collider for Higgs Factory

Abstract

A ring-based Higgs factory with a center-of-mass energy of 240 GeV residing in the existing LEP tunnel is studied at a level of concrete lattice. We found that low-emittance lattice is essential to mitigate the effect of beamstrahlung on the beam lifetime. To achieve a luminosity of $1.0\times 10^{34}{\mathrm{cm}}^{-2}{\mathrm{s}}^{-1}$, we simplified final focusing system and improved its momentum aperture by a factor of 5 to 2.5%.
