    "description": "<p>The objective of this thesis is to investigate the degree to which Delphes is usable as a substitution for GEANT, specifically in the case of tt+X events. This is done by attempting to produce simulated data using Delphes which is as close as possible to existing&nbsp;simulations made using GEANT. In the first part, the used simulation tools are reviewed and a&nbsp;workflow which isolates the effect of varying the detector level simulation is devised. In the latter part, deviations between the GEANT-based results and the Delphes-based results are investigated, and an attempt is made to determine their origin and to mitigate them by adjusting the Delphes configuartion. By comparing the deviation between Delphes&nbsp;and GEANT across simulations of different parton level processes (ttbb, ttH and ttZ), the universality of the findings is gauged.<br>\n<br>\nA repository with relevant code and configuration files exists under&nbsp;<a href=\"https://gitlab.etp.kit.edu/cn-cms/ttx-delphes/\">https://gitlab.etp.kit.edu/cn-cms/ttx-delphes/</a>.</p>",
