 Measurement of the top quark pair production cross section and simultaneous extraction of the W heavy flavor fraction at $\sqrt{s}$ = 7 TeV with the ATLAS detector at the LHC / Roe, Adam The top quark pair production cross section, $\sigma_{t\bar{t}}$, is measured in the semileptonic channel in two datasets using a binned profiled likelihood template fit to data to discriminate the signal, $t\bar{t}$, from its main background, the production of a $W$-boson in association with jets ( [...] II.Physik-UniGö-Diss-2012/04 ; CERN-THESIS-2012-476. - 167 p.

 Direct top quark decay width measurement in the $t \bar{t}$ lepton+jets channel at $\sqrt {s}$ = 8 TeV with the ATLAS experiment / Stolte-Cord to Krax, Philipp The top quark $t$ plays an essential role in the field of elementary particle physics - in particular due to its exceptional properties comprising a large mass, which approximately equals the mass of a tungsten atom, and an enormously short lifetime [...] CERN-THESIS-2017-351 ; II.Physik-UniGö-Diss-2017/03. - 256 p.
