Background MC Samples
The MC samples to model the various backgrounds are summarized in Table D.3 to Table D.6.
This includes Z/γ(∗)→ ll+jets, W → ℓν+jets, t ¯t and single-top, and di-boson productions. The
generation of some background processes are split up according the number of additional partons (that forms the corresponding jets). These samples are marked with NpX in the name, with X referring to the number of partons. The sample with the highest X-digit is inclusive, means, it contains also number of partons above X.

Danksagung
Diese Arbeit h¨atte ich ohne die Unterst¨utzung von vielen Menschen nicht durchf¨uhren k¨onnen. Als erstes m¨ochte ich mich bei meinen Betreuern Prof. Arno Straessner und Dr. Wolfgang Mader bedanken, die mir die M¨oglichkeit gaben, diese Arbeit bei Ihnen anzufertigen und immer mit vielen Ratschl¨agen zur Seite standen. Ebenso gilt mein Dank Prof. Michael Kobel der als Instituts- und ATLAS-Gruppenleiter f¨ur die guten Rahmenbedingungen der Teilchenphysik an der TU Dresden sorgte. F¨ur die vielen wichtigen Hinweise w¨ahrend der Promotion, den unz¨ahligen inter- essanten, wissenschaftlichen und nicht so wissenschaftlichen Diskussionen im B¨uro und in der Mensa m¨ochte ich auch meinen Kollegen danken, insbesondere Marcus Morgenstern, Sebastian Wahrmund, Dirk Duschinger und Lorenz Hauswald. Auch m¨ochte ich all jenen Danke sagen, die meine Zeit am IKTP begleitet haben, sowie die Forschung in Dresden angenehm machten. Ein Dankesch¨on geht auch an meine internationalen Kollegen bei ATLAS, der TauWG Community und der MSSM Higgs-Gruppe, und hier vorallem John Keller und Nikolaos Rompotis, mit denen diese Analyse zusammen durchgef¨uhrt wurde.
Der gr¨oßte Dank aber gilt meinen Eltern, meinem Bruder Falko und vorallem meiner Frau Carsta, die mich w¨ahernd der gesamten Zeit moralisch unterst¨utzt haben. Sie standen mir bei allen Pro- blemen immer mit großer Liebe zur Seite und haben trotz der langen Zeit zwischen Abschluß der Forschung und Fertigstellung dieser Schrift nie die Geduld und den Glauben an mich verloren.
