Precision luminosity measurement at LHC using two-photon production of μ+μ- pairs
The application of the two-photon process pp → pp + μ+μ- for the luminosity measurements at LHC with the ATLAS detector is considered. The expected accuracy of the absolute offline luminosity determination is 1-2% for the luminosity range of 1033-1034 cm-2 s-1. The preliminary cross-section estimates done for LHCb promise the same level of the luminosity measurement accuracy at L = 2 × 1032 cm-2 s-1. © 2002 Elsevier Science B.V. All rights reserved.
