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, ...
Vector-meson interactions, dynamically generated molecules, and the hadron spectrum
(2018-09-19)
We study the lowest-lying vector-meson interactions and dynamically generated bound states. Therefore, these bound states are studied as hadronic molecules. We demonstrate that some unitarization methods are not well-defined ...
Knotenwichtigkeiten in räumlich ausgedehnten dynamischen Systemen
(2018-08-28)
Ausgedehnte komplexe dynamische Systeme können eine Vielzahl von faszinierenden emergenten Phänomenen aufweisen. Viele solcher Systeme bestehen aus einer großen Anzahl interagierender Subsysteme. Es bietet sich daher an, ...
Yukawa Couplings from D-branes on non-factorisable Tori
(2018-08-15)
In this thesis Yukawa couplings from D-branes on non-factorisable tori are computed. In particular intersecting D6-branes on the torus, generated by the SO(12) root lattice, is considered, where the Yukawa couplings arise ...
Test beam and simulation studies on High Resistivity CMOS pixel sensors
(2018-09-21)
The Compact Linear Collider CLIC is an option for a future electron positron collider at CERN, with a centre of mass energy up to 3 TeV. The demanding physics goals at CLIC require a lightweight silicon vertex detector and ...
Associated Production of a Top Quark and a Z Boson in pp Collisions at √s = 13 TeV Using the ATLAS Detector
(2018-09-26)
The production of a top quark in association with an Z boson is studied using 36.1 fb-1 of proton-proton collision data collected by the ATLAS experiment at the LHC in 2015 and 2016 at a centre-of-mass ...
Search for solar chameleons with an InGrid based X-ray detector at the CAST experiment
(2018-08-15)
Chameleons are particles with a density dependent effective mass and couplings to matter as well as photons. They are introduced in modifications to General Relativity involving scalar fields and aiming at explaining Dark ...
Transporteigenschaften und Reaktivität von Bor-hydrid-hydrat-oxidsodalithen
(2018-07-13)
In dieser Arbeit wurden Borsodalithe bezüglich ihrer Eignung als Wasserstoffspeicher und BH$_4^-$-haltige Salze in Kooperation mit der experimentellen Arbeitsgruppe textit{Rüscher} quantenchemisch mit periodischen ...
Characterization and Quality Control of RD53A Readout Chips and Modules for the ATLAS ITk Pixel Detector
(2021-12-16)
In preparation of the upcoming high-luminosity upgrade of the Large Hadron Collider, the detectors of the major high-energy physics experiments at the accelerator facility will be upgraded as well. In case of the ATLAS ...
Intranukleäre Mobilität und Export der kleinen Untereinheit in humanen Zellen
(2018-06-18)
Die Ribosomenbiogenese ist ein essentieller Prozess aller lebender Zellen, da ohne funktionale Ribosomen die Proteinsynthese in der Zelle zusammenbricht. Da der Prozess der Ribosomenbiogenese demnach so wichtig ist, wurde ......
