TL;DR
This paper evaluates the future prospects for achieving extremely high theoretical precision in luminosity measurements at upcoming lepton colliders, emphasizing the need for improvements beyond current standards.
Contribution
It provides an analysis of the required precision improvements and discusses potential paths to surpass current theoretical accuracy goals for future collider experiments.
Findings
Current LEP precision tags are around 0.05-0.06%.
Future colliders aim for at least 0.01% precision at M_Z.
Strategies to improve theoretical precision are discussed.
Abstract
The LEP precision physics requirements on the theoretical precision tag for the respective luminosity were () at , 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 to at least 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 and proposed higher energy scenarios.
