Integrated luminosity measurement at CEPC
Abstract
The very forward region is one of the most challenging regions to instrument at a future 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 , initially proposed for FCC, is also discussed for the CEPC beams.
