Luminosity measurement at ILC    [PDF]

In this paper we propose the method of luminosity measurement at the future linear collider ILC that estimates and corrects for the impact of the dominant sources of systematic uncertainty originating from the beam-induced effects and the background from physics processes. Some systematic corrections can be done in a simulation independent manner. With the specific event selection, different from the isolation cuts based on topology of the signal used at LEP and with the corrective methods we introduce, overall systematic uncertainty of the luminosity measured in the peak region above 80% of the nominal center-of-mass energy meets the physics requirements to be at the permille level at all ILC energies.
