Comparison of dilepton events in simulation and $pp$ collision data at $\sqrt s = 8\tev$ gathered by the ATLAS detector at the LHCIsacson, Max January 2014 (has links)
This thesis presents the results of a comparison between collision data and simulations based on Monte Carlo methods. The experimental dataset consists of $20.3\,\mathrm{fb}^{-1}$ of proton-proton collision data at $\sqrt s = 8\tev$ collected during 2012 by the ATLAS experiment located at the Large Hadron Collider. The final state used is $e\mu + \mathrm{jets}$. Four regions are defined, pretag ($\geq0$ jets, $\geq0$ $b$-jets), $\geq1$-tag ($\geq1$ jets, $\geq1$ $b$-jets), $\geq2$-jet ($\geq2$ jets, $\geq0$ $b$-jets), and 2-tag ($\geq2$ jets, 2 $b$-jets). Data and simulations are consistent in all regions considered.
