Overview of Future e+e- Colliders from the Perspective of Theoretical Luminosity Precision

After giving an overview of the seriously planned future e+ e- colliders, we discuss the path to the required theoretical luminosity precision. Specifically, for the FCC-ee, CEPC 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 MZ, where the former (latter) LEP result has (does not have) the pairs correction. At the FCC-ee at MZ one needs improvement to 0.01%, for example. We present the status of the realization of the road 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-ee350, ILC500, ILC1000, and CLIC3000 setups.

Our colloquium is on every Wednesday 4-5PM US central time. You can see the talk schedule at https://www.baylor.edu/physics/colloquia. The streaming will start a little before each colloquium talk starts.
