Measurement of the top-antitop and $Z^{0}$-boson production cross sections and their ratio in the dileptonic decay channels at $\sqrt{s} =$ 7 TeV with the CMS experiment
In this thesis, the production of Z0 boson and top-quark pairs is studied. In particular, the decays into two leptons are analyzed. The data recorded by the CMS experiment at the LHC in 2011 is used, corresponding to an integrated luminosity of 1.14 fb−1. The candidates are selected by requiring two...
