 Measurement of Top-Quark Pair Production Cross Sections and Calibration of the Top-Quark Monte-Carlo Mass using LHC Run I Proton-Proton Collision Data at square $\sqrt{s}= 7 and 8 TeV with the CMS Experiment. / Kieseler, Jan (DESY) ; Lipka, Ekaterina (dir.) (DESY) In this thesis, measurements of the production cross sections for top-quark pairs andthe determination of the top-quark mass are presented. Dileptonic decays of top-quarkpairs (tt) with two opposite-charged lepton (electron and muon) candidates in the ﬁnalstate are considered. [...] CERN-THESIS-?; CMS-TS-2016-007.- 2016 - 166 p.
