Measurement of the integrated luminosity and the luminosity spectrum at the linear collider
The high charge density and high energy at future linear colliders will present challenges to the luminosity measurement that have not been there in the past. The intense electromagnetic interaction between the electron bunches influences the luminosity measurement at the level of several percent. Precise correction of the beam-beam effects, based on experimentally measurable quantities, is described here. In addition, a comprehensive list of systematic effects in luminosity measurement is given, with their individual contributions to the final uncertainty of the luminosity figure.
