Integrated luminosity measurement at CEPC

Instrumentation and Detectors 2022-02-01 v3 High Energy Physics - Experiment

Abstract

The very forward region is one of the most challenging regions to instrument at a future e+ee^+e^- collider. At CEPC, machine-detector interface includes, among others, a calorimeter dedicated for precision measurement of the integrated luminosity at a permille level or better. Here we review a feasibility of such precision, from the point of view of luminometer mechanical precision and positioning, beam-related requirements and physics background.A method of the effective center-of-mass determination from e+eμ+μe^+e^- \to \mu^+\mu^-, initially proposed for FCC, is also discussed for the CEPC beams.
