Abstract

The LEP precision physics requirements on the theoretical precision tag for the respective luminosity were 0.054 % (0.061%) at M_Z, where the former (latter) LEP result has (does not have) the pairs correction. For the contemplated FCC-ee, ILC, and CEPC Higgs/EW factories, one needs improvement at M_Z to at least 0.01% for the theoretical precision tag. We discuss the paths one may take to even exceed this latter goal and present an update on the current expectations for both M_Z and proposed higher energy scenarios.
