Studies into tau reconstruction, missing transverse energy and photon induced processes with the ATLAS detector at the LHC
(2011-10-11)
The ATLAS experiment is currently recording data from proton-proton collisions delivered by CERN's Large Hadron Collider. As more data is amassed, studies of both Standard Model processes and searches for new physics beyond ......
Topological string theory, modularity and non-perturbative physics
(2011-09-28)
In this thesis the holomorphic anomaly of correlators in topological string theory, matrix models and supersymmetric gauge theories is investigated. In the first part it is shown how the techniques of direct integration ...
Computational Simulation of Trabecular Bone Distribution around Dental Implants and the Influence of Abutment Design on the Bone Reaction for Implant-Supported Fixed Prosthesis
(2011-09-30)
Computational modelling of trabecular bone distribution based on the remodelling process is a challenging issue. Up to now, most of bone remodelling models attempted to describe the remodelling process with noncemented ...
Search for Supersymmetry and kinematic endpoint measurement in final states with two tau leptons with the ATLAS detector at the LHC
(2011-10-21)
Discovery prospects for Supersymmetry in final states with at least two tau leptons and large missing transverse energy are evaluated for LHC proton-proton collisions measured with the ATLAS detector. In a first study based ......
Das Entdeckungspotential von Supersymmetrie mit Endzust¨anden aus mindesten zwei Tau Leptonen und fehlender Transversalenergie in Proton-Proton Kollisionen wird untersucht, sowie die M¨oglichkeit einer Messung des Endpunktes ......

Searching for High-energy Neutrinos from Supernovae with IceCube and an Optical Follow-up Program
(2011-10-21)
In violent astrophysical processes high-energy neutrinos of TeV to PeV energies are expected to be produced along with the highest energy cosmic rays. The acceleration of nuclei to very high energies is assumed to takes ...
Few-Body Physics in Quantum Gases
(2011-10-25)
Few-body effects play an important role for the understanding of ultracold quantum gases. We make use of an effective field theory approach to investigate various aspects of universal few-body physics close to a Feshbach ...
Optische Spektroskopie von PTCDA auf Alkalihalogenidoberflächen: vereinzelte Moleküle und Monolagen
(2012-08-03)
In dieser Dissertation wurden die strukturellen und optischen Eigenschaften organischer p-konjugierter Moleküle, die auf einer einkristallinen Oberfläche adsorbiert waren, untersucht. Die Untersuchungen sind damit relevant ...
Trapping fermionic potassium atoms in a quasi-electrostatic optical dipole potential
(2012-08-03)
Ultracold quantum gases have become a frequently used tool for the investigation of a variety of physical issues within the last decade, ranging from general questions in quantum physics up to special topics, e.g. quantum ...
Measurement of polarization observables in the reaction γp →pπ0π0 using linearly polarized photons with the CBELSA/TAPS experiment
(2012-08-10)
The spectrum and the properties of baryon resonances can be studied using photons with energies appropriate to excite baryonic states. Double meson photoproduction allows access to cascading resonance decays via other ......
Bestimmung der Doppelpolarisationsobservablen G in π0-Photoproduktion
(2012-07-18)
Die Hadronenspektroskopie stellt zur Untersuchung des inneren Aufbaus der Nukleonen und damit der Wechselwirkung zwischen den Konstituenten, den Quarks, ein geeignetes Mittel dar. Die bereits gemessenen Anregungszustände ...
