Z →ττ Cross Section Measurement and ττ Mass Reconstruction with the ATLAS Detector at the LHC
(2012-11-14)In this dissertation, the Z to tautau decay where one τ decays leptonically and the other one hadronically is presented. The process is studied with data collected from the ATLAS experiment in pp collisions at c-m-s = 7 TeV ... -
Measurement of the inclusive <i>tγ</i> cross section at √<i>s</i> = 7 TeV with the ATLAS detector
(2012-06-12)A first measurement of the ttγ cross section in pp collisions at the LHC using 1.04 fb-1 of data taken with the ATLAS detector is presented. A total of 122 candidate events were identified in the single electron and single ... -
Precision Measurements of the Top Quark Pair Production Cross Section in the Single Lepton Channel with the ATLAS Experiment
(2012-05-10)Two precision measurements of the top quark pair production cross section in the lepton+jets channel are accomplished using data taken by the ATLAS experiment at the Large Hadron Collider at CERN. The data corresponds to ... -
Measurement of the Top Quark Pair Production Cross Section and Simultaneous Extraction of the W Heavy Flavor Fraction at √s = 7 TeV with the ATLAS Detector at the LHC
(2012-04-27)The top quark pair production cross section, σtt, is measured in the semileptonic channel in two datasets using a binned profiled likelihood template fit to data to discriminate the signal, tt, from its main background, ... -
Measurement of the charge asymmetry in top quark pair production in in pp collision data at √s = 7 TeV using the ATLAS detector
(2012-03-22)A measurement of the charge asymmetry in the production of top quark pairs in the semileptonic decay channel has been performed. A dataset corresponding to an integrated luminosity of 1.04 fb-1, btained at a centre-of-mass ... -
Calorimeter-Based Triggers at the ATLAS Detector for Searches for Supersymmetry in Zero-Lepton Final States
(2012-03-09)This thesis consists of three closely related parts. An analysis of data recorded by the ATLAS detector in 2010 in proton-proton collisions at a center-of-mass energy of 7 TeV with an ...
