Abstract
The luminosity calibration for the ATLAS detector at the LHC during pp collisions at ���s = 7 TeV in 2010 and 2011 is presented. Evaluation of the luminosity scale is performed using several luminosity-sensitive detectors, and comparisons are made of the long-term stability and accuracy of this calibration applied to the pp collisions at ���s = 7 TeV. A luminosity uncertainty of ��L/L = ��3.5% is obtained for the 47 pb-1 of data delivered to ATLAS in 2010, and an uncertainty of ��L/L = ��1.8% is obtained for the 5.5 fb-1 delivered in 2011. �� 2013 CERN for the benefit of the ATLAS collaboration.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
