Studien zur Entfaltung kinematischer Verteilungen in der elektroschwachen Streuung von W- und Z-Bosonen am LHC MK

For the comparison between kinematic distributions in the WZ -scattering measured by the ATLAS-detector and other measurements or theory predictions, it is necessary to consider the impact of detector effects such as the limited efficiency and resolution. One way to eliminate the detector impact on the data is unfolding. In this bachelor thesis Monte Carlo data of the transverse mass $M_T$ (𝑊𝑍), the transverse momentum $M_T$ (𝑍) and the numb er of jets in the electroweak scattering of W - and Z -bosons are unfolded. The unfolding process is studied at different integrated luminosities which can b e partially reached in the Run 2 of the LHC. At first a method for the bin optimization is chosen in preparation of the unfolding. Different unfolding methods are used to calculate the unfolding result and its statistical and systematic uncertainties. Subsequently the uncertainty caused by the unfolding process is determined. Finally statistical fluctuated Monte Carlo pseudo data is unfolded to gain an impression of how the unfolding results of real measured data might look like. The procedure of unfolding, which is used in this thesis, is kept general and could b e applied to other data distributions.
