Entwicklung einer Spurkammer für das Studium von Driftfeld-Kalibrationsmethoden
(2022-06-07)
Bei der Erforschung von Materie hat man sich in der Geschichte schrittweise, durch Beobachtungen und Modelle, an ihre untergeordneten Strukturen herangetastet. Aus heutiger Sicht sind Quarks und Gluonen, neben den Elektronen, ...
Identification of low-valent iron-porphyrins: Electronic structure and reactivity towards CO2 reduction
(2022-01-25)
The need to close the carbon cycle becomes urgent as concentration of CO2 in the earth atmosphere increases exponentially. Electrochemically-mediated conversion of CO2 into biofuels is a possible ...
Nachweis von vorwärtsgestreuten Protonen in photoninduzierten Reaktionen am Nukleon
(2015-03-20)
Die Untersuchung von Anregungsspektren von Hadronen kann zum besseren Verständnis der starken Wechselwirkung beitragen. Eine Methode ist die Photoproduktion von Mesonen am Nukleon. Aufgrund der Breite der angeregten Zustände ...
A gateway to new physics: direct measurement of the top Yukawa coupling to the Higgs boson
(2017-08-23)
The top quark has the largest Yukawa coupling in the Standard Model, is the main contribution to the Higgs mass $m_H$ corrections and defines the evolution of the Higgs effective potential with the energy, together with ...
Dynamical Effects in Heavy-Fermion Systems
(2025-03-27)
When atoms in solids have unfilled d- or f-orbitals, local Coulomb interaction often becomes non-negligible due to the strongly localized nature of those orbitals. A hallmark effect of such systems is the formation of a ......
Effective actions from string and M-theory: compactifications on G2-manifolds and dark matter in the KL moduli stabilization scenario
(2018-09-26)
In this thesis we study the emergence of four-dimensional effective actions from compactifications of higher-dimensional string/M-theory and explore some of their phenomenological implications.
In order to compactify ......

Final-state interactions in heavy-meson decays
(2018-08-15)
In the last decade the investigation of the heavy-meson sector has gained in importance, in particular for precision tests of the Standard Model and exploration of the physics beyond, such as CP violation. Experimentally, ...
Tracing the effects of stellar feedback on molecular gas from simulations to observations
(2026-05-12)
The interstellar medium (ISM) is a turbulent, multi-phase medium with a hierarchical structure consisting of molecular clouds (MCs), clumps, and cores. Stars form in dense cores and, over their evolution, inject mass, ...
Exploration of advanced CMOS technologies for new pixel detector concepts in High Energy Physics
(2018-04-19)
This thesis presents the author’s original concepts for the development of radiation hard monolithic pixel sensors that can replace hybrid pixel sensors in high energy physics experiments. It presents one of the first ...
Charakterisierung von bildgebenden Pixeldetektoren aus Si und CdTe ausgelesen mit dem zählenden Röntgenchip MPEC 2.3
(2007)
In dieser Arbeit wurden Detektoren mit Si- und CdTe-Sensoren aufgebaut, die über die Eigenschaft verfügen, einzelne Photonen durch Zählen nachzuweisen. Als Auslesechip wurde der MPEC 2.3 verwendet, der aus 32 x 32 Pixeln ...
