Uncertainties from metrology in the integrated luminosity measurement with the updated design of a detector at CEPC

Ivan Smiljanic, Ivanka Bozovic, Goran Kacarevic

In order to measure integrated luminosity with a required precision of $10^{-4}$ at the $Z^0$ pole, proposed CEPC $e^{+}{e}^{-}$ collider requires a luminometer, a specially designed…
