Molecular gas in hydrodynamical simulations of galaxy formation
(2022-09-26)
Observations of nearby galaxies indicate a strong correlation between their molecular gas content and their star formation rate. This leads to the conclusion that molecular hydrogen – the most abundant molecule in galaxies ...
The Quest for the η and η' Transition Form Factors: A Stroll on the Precision Frontier
(2022-10-04)
An important precision test of the Standard Model of Particle Physics is posed by the prediction of the anomalous magentic moment of the muon. Currently, a deviation of about 4.2σ persists between the experimental average ......
Development and Characterisation of Passive CMOS Sensors for Pixel Detectors in High Radiation Environments
(2022-10-07)
With the upgrade of the Large Hadron Collider (LHC) to the High-Luminosity LHC (HL-LHC), the instantaneous luminosity increases by a factor of five with respect to its design value from 2027. To keep the detectors at the ...
Geometric approach to the Feynman integrals
(2022-10-07)
In this PhD thesis, the Feynman integrals are evaluated using an algebraic geometry approach known in string theory. The GKZ description of periods and certain classes of relative periods on Calabi-Yau (l - 1)-folds ......
Evaluation of a Serial Powering Scheme and its Building Blocks for the ATLAS ITk Pixel Detector
(2022-11-02)
The high luminosity upgrade for the Large Hadron Collider (LHC) at CERN requires a complete redesign of the current inner detectors of ATLAS and CMS. These new inner detectors will consist of all-silicon tracking detectors, ...
Experimental studies on small diameter carbon dioxide evaporators for optimal Silicon Pixel Detector cooling
(2020-12-18)
Since recent years the Large Hadron Collider at CERN and its experiments are the subject of upgrade programs, which are necessary to increase the foreseen collision rates and the amount of data to be gathered for the ...
Exploring Non-Equilibrium in Ultracold Fermi Gases and Machine Learning in Physics
(2021-05-21)
This thesis covers two fields of research carried out in the context of ultracold Fermi gases: Non-equilibrium physics in the BEC-BCS crossover and the use of machine learning methods in physics.
The BEC-BCS ...
The BEC-BCS ...
A formalism for a consistent treatment of two-pion interactions in heavy meson decays
(2020-10-14)
The best-established theory of particle physics up to now is the Standard Model. The theory of strong interactions called quantum chromodynamics (QCD) is a part of it. QCD leads to a wide range of phenomena, which still ...
Strong Coupling between Small Atomic Ensembles and an Open Fiber Cavity
(2018-04-12)
In this work I present the experimental realization of a versatile platform for the interplay between light and matter at the single-quanta level. In particular, I demonstrate the high cooperativity of small ensembles of ......
Design eines neuen Lichtpulsersystems sowie Aufbau und Inbetriebnahme der neuen APD Auslese für das Crystal-Barrel-Kalorimeter
(2018-02-21)
Um ein tieferes Verständnis von der Struktur der Nukleonen sowie der starken Wechselwirkung zu erhalten, werden am CBELSA/TAPS-Experiment Doppelpolarisationsmessungen in der Meson-Photoproduktion durchgeführt. Die ...
