Abstract:
Lepton fiavor violating decays are a unique probe of new physics. They might be related to the mechanism of neutrino mass generation, to the spontaneous breaking of supersymmetry, or to new interactions at high energies, above and below the GUT scale. Their detection would give an unmistakable signal of physics beyond the Standard Model and its minimal extensions, and could be the first manifestation of supersymmetric effects. And it would certainly mark the beginning of a new era in particle physics. Among them, µ → eϒ and τ → µϒ offer excellent experimental perspectives. The limits on these decays are already impressive and significant improvements are expected in the next few years. Thus, their role in constraining and perhaps discovering new physics will be reinforced by future experiments. Recently, motivated by these experimental efforts, by the study of neutrino mass models, and by the data from ν oscillation experiments, µ → eϒ and τ → µϒ have received particular attention. Different aspects regarding these processes were investigated in papers [1, 2, 3, 4]. This thesis is based on those works. In the first chapter, the motivation and the general framework are introduced. A critical review of some assumptions commonly employed in the computation of lepton fiavor violating decays is presented in chapter two. We investigate, in the third chapter, the implications, within a particular SO(10) model, µ → eϒ and τ → µϒ for the determination of the viable parameter space, and we confront the perspectives for their detection against accelerator experiments in the search for supersymmetry. Finally, in chapter four we address the relevance of the gaugino spectrum on the computation of BR(µ → eϒ).

Abstract:
Supersymmetrie (SUSY) ist eine der am besten motivierten Erweiterungen des Standardmodells, und Suchen nach Hinweisen auf Supersymmetrie am LHC sind ein wichtiger Beitrag zum Verständnis von neuer Physik. Das Thema dieser Doktorarbeit ist die Analyse von zwei SUSY-Szenarien unter Verwendung von 20.3 fb−1 an ATLAS Daten, die bei einer Schwerpunktenergie von 8 TeV aufgezeichnet wurden. Den Hauptteil der Arbeit stellt eine Untersuchung des "Nicht-Universelle Higgs Massen Modells mit Gaugino Mediation" (NUHMG) mit Tau-Sneutrino als NLSP dar. Es wurde gezeigt, dass NUHMG unter Verwendung von Ereignissen ohne Leptonen, mit mehreren Jets, und fehlendem Transversalimpuls zu finden sein müsste. Eine neue Methode zur schnellen Optimierung unter Verwendung von multivariaten Methoden wurde entwickelt und in die Analyse eingebracht. Da kein signikanter Überschuss an Ereignissen in den untersuchten Daten beobachtet wurde, wurden experimentell ausgeschlossene Parameterbereiche des NUHMG-Modells bestimmt (bei einem Konfidenzniveau von 95 Prozent). Hierbei wurden Squark und Gluino Massen unterhalb von 1250 GeV bzw. 1400 GeV ausgeschlossen. Das zweite SUSY-Modell, das in dieser Doktorarbeit untersucht wird, ist das Nicht-Universelle Higgs Massen Modell (NUHM) mit Neutralino als LSP, welches innerhalb der Theorie der “Radiatively Driven Natural SUSY” (RNS) motiviert ist. Eine Datenanalyse mit einer statistischen Kombination von Ereignissen mit 2 bis 4 Leptonen wurde durchgeführt. Da kein signikanter Überschuss von Ereignissen beobachtet wurde, wurden ausgeschlossene Parameterbereiche des RNS-NUHM Modells bestimmt. Der größte Beitrag kommt hierbei von der Analyse mit 3 Leptonen, und es werden Werte von m1/2
Supersymmetry (SUSY) is one of the best motivated extensions of the Standard Model. The subject of this thesis is the analysis of two SUSY scenarios using 20.3 fb-1 of ATLAS data at 8 TeV center of mass energy. The main topic is a study of the Non-Universal Higgs Masses model with Gaugino mediation and Tau-Sneutrino NLSP (NUHMG). A study showed that NUHMG can be found using Squark and Gluino production, using final states with zero leptons of transverse momenta higher than 10 GeV, multiple jets and missing transverse energy. A new method for fast optimisation using multivariate techniques was developed for the analysis with 2-6 jets and missing transverse momentum. No significant excess of data has been seen, and 95 percent CL exclusion limits have been set on the model, where Squark and Gluino masses are excluded up to 1250 and 1400 GeV respectively. Second SUSY model studied, is the Non-universal Higgs Masses model with Neutralino LSP (NUHM). It is well motivated in the framework of Radiatively Driven Natural Supersymmetry (RNS). A data analysis using a statistical combination of 2, 3 and 4 leptons has been performed. No significant excess of data has been observed, and 95 percent CL exclusion limits have been set. They reach up to 300 GeV in m1/2, and extend up to the highest tested value of μ = 500 GeV. In addition to physics analyses, a program developed for online monitoring of the ATLAS trigger, called Trigger Presenter (TriP), is described in this thesis.

Abstract:
The chapter discusses advances in matter-wave optics with complex molecules, generalizing Young’s double slit to high masses. The quantum wave-particle duality is visualized by monitoring the arrival patterns of molecules diffracted at nanomechanical masks. Each molecule displays particle behavior when it is localized on the detector; however, the overall interference pattern requires their delocalization in free flight. Internal particle properties influence the de Broglie waves in the presence of surfaces or fields—even in interaction with atomically thin gratings. To probe the quantum nature of high-mass molecules, universal beam splitters are combined in a multi-grating interferometer to observe high-contrast matter-wave fringes even for 500 K hot molecules, containing 810 atoms with a mass of 10 000 amu. The high sensitivity of the nanoscale interference fringes to deflection in external fields enables non-invasive measurements of molecular properties. The chapter concludes by discussing research on beam techniques that extend molecular quantum optics to large biomolecules.
