Abstract

For both the FCC-ee and the ILC, to exploit properly the respective precision physics program, the theoretical precision tag on the respective luminosity will need to be improved from the analogs of the $0.054% (0.061%)$ results at LEP at $M_{Z}$ , where the former (latter) LEP result has (does not have) the pairs correction. At the FCC-ee at $M_{Z}$ one needs improvement to $0.01%$ , for example. We present an overview of the roads one may take to reach the required $0.01%$ precision tag at the FCC-ee and of what the corresponding precision expectations would be for the FCC-ee $_{350}$ , ILC $_{500}$ , ILC $_{1000}$ , and CLIC $_{3000}$ setups.
