Cosmological Investigations On Large And Small Scales
(2017-03-03)
The standard model of cosmology, founded on Einstein’s theory of gravity and on the Cosmological Principle (CP), has been understood as being successful in providing explanations for many observations so far. However, it ...
Die externe Strahlführung für Detektortests X3ED an der Elektronen-Stretcher-Anlage ELSA
(2017-12-12)
Um das Verständnis des Aufbaus der Materie zu erweitern sind Experimente mit hochenergetischen Teilchen erforderlich. Diese Teilchenstrahlen werden beispielsweise durch Kreisbeschleuniger bereitgestellt. Aufseiten der ...
Hadronic Electroweak Processes in a Finite Volume
(2017-11-27)
In the present thesis, we study a number of hadronic electroweak processes in a finite volume. Our work is motivated by the ongoing and future lattice simulations of the strong interaction theory called quantum chromodynamics. ...
Metal-air Batteries: RRDE and EC-SPM Studies of Electrode Kinetics and Electrode Structure
(2017-09-26)
Metal air batteries are the energy storage devices, which possess the advantages of low cost, non-toxic, non-polluting, high theoretical specific energy, etc. Consequently, they received extensive attention and are considered ...
Sarah Goes Left and Right Looking Beyond the Standard Model and Meets Susy
(2017-09-12)
Progress in the search for physics beyond the Standard Model (BSM) proceeds through two main avenues. The frst requires the development of models that address the host of theoretical and experimental deficiencies of the ...
Analyse komplexer dynamischer Systeme durch Charakterisierung retardierter, gerichteter und gewichteter Interaktionen
(2017-11-27)
Die Erforschung der Dynamik ausgedehnter komplexer Systeme stellt seit jeher eine der großen Herausforderungen in verschiedenen Bereichen der Wissenschaft dar, von Physik, über Informatik, Biologie, Geowissenschaften und ...
Production and PAC studies of 83Rb/83mKr solid state calibration sources for the KATRIN experiment
(2017-12-13)
The KATRIN experiment studies the tritium beta-decay kinematics to deduce the neutrino mass. The emitted electrons' kinetic energy close to the beta-spectrum's endpoint is analysed using a high-precision Magnetic Adiabatic ...
Search for Flavour Changing Neutral Currents through Single Top-Quark Production at √s= 8 TeV with the ATLAS Detector
(2017-12-20)
Flavour changing neutral current processes are highly suppressed in the Standard Model due to the Glashow-Iliopoulos-Maiani mechanism. However, many extensions of the Standard Model predict the existence of these processes ......
Topics in chiral perturbation theory for charmed mesons
(2017-10-10)
This thesis is concerned with topics in chiral perturbation theory for pseudoscalar charmed mesons in a manifestly Lorentz-invariant way. After constructing the chiral effective Lagrangian describing spinless matter fields ...
Exploring exotic states with twisted boundary conditions
(2017-10-24)
The goal of this thesis is to develop methods to study the nature and properties of exotic hadrons from lattice simulations. The main focus lies in the application of twisted boundary conditions. The thesis consists of a ...
