Measurement of the Top Quark Pair Production Cross Section and an in-situ B-tagging efficiency Calibration with ATLAS in pp Collisions at √s = 7 TeV in Dilepton Final States
We present a measurement of the top anti-top quark (ttbar)production cross section in the dilepton final states from proton-proton collisions at a center of mass energy at 7 TeV at the LHC. A b-tagging algorithm based on tracks displaced from the event interaction vertex is applied to identify bott...
