Measurement of the beam and helicity asymmetries in the reactions γp → pπ0 and γp → pη
(2019-09-24)
Nucleons are bound states composed of quarks and gluons. The study of the nucleon excitation spectra gives insight into the underlying dynamics between quarks and gluons that are governed by the strong interactions and ......
Measurement of Tau Polarisation in Z/γ* → ττ Decays in Proton–Proton Collisions at ATLAS
(2019-12-19)
This thesis presents a measurement of the tau polarisation in Z/gamma*->tautau decays at ATLAS using a dataset of proton–proton collisions recorded at a centre-of-mass energy of sqrt(s) = 8 TeV that amounts to an integrated ...
Pulsar Searching and Timing with the Arecibo and Effelsberg Radio Telescopes
(2019-08-13)
Pulsars are rapidly rotating, highly magnetized, neutron star remnants of the supernova explosions of massive stars. In this thesis, I mostly focus on recycled pulsars, which are old (approx 100 million years old) neutron ...
Fast diffusion MRI based on sparse acquisition and reconstruction for long-term population imaging
(2019-11-21)
Diffusion weighted magnetic resonance imaging (dMRI) is a unique MRI modality to probe the diffusive molecular transport in biological tissue. Due to its noninvasiveness and its ability to investigate the living human brain ...
Optimierung des Beschleunigerbetriebs für Experimente zur Hadronen- und Detektorphysik an der Elektronen-Stretcher-Anlage ELSA
(2019-07-30)
An der Elektronen-Stretcher-Anlage ELSA des Physikalischen Instituts der Universität Bonn werden an den beiden Experimentierplätzen Crystal Barrel/TAPS und BGO-OD Experimente zur Untersuchung der inneren Struktur von ...
Optical investigations on PTCDA on KCl(100): Superradiant aggregates and single molecules
(2019-08-23)
In the present work, condensed and diluted phases of 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA) were investigated on thin KCl(100) films on the Ag(100) surface. The samples were structurally characterized by spot ...
Anordnung und Test der Detektor-Submodul-Komponenten für die Vorwärts-Endkappe des PANDA-EMC
(2019-07-16)
Ein großer Schritt zum besseren Verständnis des Standardmodells der Teilchenphysik ist die Beschreibung der Quantenchromodynamik (QCD) im Bereich der nicht störungstheoretisch berechenbaren Energieüberträge. In diesem ......
Matching and test of the forward-endcap detector-submodule-components for the PANDA-EMC
A large step towards a better understanding of the standard model of particle physics is the description of ......

Search for Squarks and Gluinos in τ-lepton Final States with the ATLAS Experiment
(2019-09-24)
Suche nach Squarks und Gluinos in τ-Lepton Endzuständen mit dem ATLAS Experiment
Das erfolgreiche und wohletablierte Standardmodell der Teilchenphysik ist in der Lage, die Mehrheit der beobachteten ...

String Compactifications from the Worldsheet and Target Space Point of View
(2019-08-29)
This thesis presents research on compactifications of type II superstring theories, combining worldsheet and target space approaches. This is achieved by using supersymmetric gauge theory techniques together with geometrical ...
Radio Continuum of Galaxies with H2O-Megamaser-Disks
(2019-11-08)
Galaxies with H2O-megamaser-disks are low luminosity active galaxies where 22GHz H2O-maser emission is detected in their accretion disk surrounding the central supermassive black hole (SMBH). Furthermore, ...
