Determination of Integrated Luminosity via W and Z Boson Production with the ATLAS Detector

Abstract

The possibility to determine the recorded integrated luminosity via the measurements of the W and Z boson production cross-sections with the ATLAS detector is discussed. The current results based on 2010 data are briefly summarized. Special attention is drawn to theoretical uncertainties of the measurement. The latter give a large contribution to the systematic uncertainties of the measurements. An outlook on the expected precision of an analysis based on 1fb-1 is given and the implications on a possible luminosity determination are discussed.Comment: presented at the LHC Lumi Days: LHC Workshop on LHC Luminosity Calibration, 13-14 January 2011, CERN, Geneva, Switzerland; CERN-Proceedings-2011-001, pp. 22-2
