Shocks in the interstellar medium
(2014-01-09)
Shocks are ubiquitous in the interstellar medium (ISM), occurring whenever large pressure gradients lead to fluid-dynamical disturbances that move at a velocity that exceeds the local sound speed. As shocks dissipate kinetic ...
Chemical Vapour Deposition Diamond: Charge Carrier Movement at Low Temperatures and Use in Time-Critical Applications
(2014-01-27)
Diamond, a wide band gap semiconductor with exceptional electrical properties, has found its way in diverse fields of application reaching from the usage as a sensor material for beam loss monitors at particle accelerator ...
Systematic Study of Hadronic Molecules in the Heavy Quark Sector
(2014-01-17)
In this work we have studied properties of hadronic molecules in the heavy quark sector. These have become increasingly important since from the beginning of this century a large number of states have been measured that ...
Properties of pseudoscalar flavor singlet mesons from lattice QCD
(2014-02-18)
The central topic of this work are masses and mixing parameters of the η-η' system, which are investigated within the framework of Wilson twisted mass lattice QCD, using gauge configurations provided by the European Twisted ...
High bandwidth pixel detector modules for the ATLAS Insertable B-Layer
(2014-02-19)
The investigation of the nature of the recently discovered electro-weak symmetry breaking mechanism of the standard model of particle physics as well as the search for physics beyond the standard model with the LHC require ...
Few-Body Systems in a Shell-Model Approach
(2014-03-14)
In this thesis, I introduce and compare an implementation of two different shell models for physical systems consisting of multiple identical bosons.
In the main part, the shell model is used to study the energy ...

Developing and evaluating new micropattern gas detectors
(2014-05-05)
Micropattern gas detectors (MPGDs) were introduced in the late 1980s in order to overcome the limited rate capability of traditional proportional counters. Thanks to their microscopic electrode structures, MPGDs are faster ...
Baryon resonances in pion- and photon-induced hadronic reactions
(2014-04-23)
The aim of the present work is the analysis of the baryon spectrum in the medium-energy regime. At those energies, a perturbative treatment of Quantum Chromodynamics, that is feasible in the high-energy regime, is not ...
Molecular Outflows in Star Forming Regions
(2014-05-21)
This thesis work focus on the study of the molecular emission from outflows produced by jets in regions of star formation. After introducing the topic of star formation, and in particular its related outflow process, a ...
Electric Dipole Moments of Light Nuclei in Chiral Effective Field Theory
(2014-05-08)
Electric dipole moments (EDMs) break parity (P) and time-reversal (T) symmetry and thus, by the CPT theorem, CP-symmetry. Once measured, they will be unambiguous signs of new physics since ...
