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 ......

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 ...
Strukturwandel von Chalkogen-Polykationen unter Druck
(2019-08-29)
Im Rahmen dieser Arbeit wurden die strukturellen Umwandlungen von Tellur- und Selen-Polykationen führenden Festkörpern unter dem Einfluss von hohem Druck untersucht. Einkristalle der zu untersuchenden Substanzen in geeigneter ......
Structural change of chalcogen polycations under pressure
This study is about high pressure phase transitions of mostly tellurium polycationic structures. Single crystals of roughly 0,1 mm size were ......

Top-quark pair production in association with a Z boson in the final state with four charged leptons
(2019-10-29)
The production cross section of a top-quark pair in association with a Z boson is measured in the channel with four reconstructed leptons, using 36.1 fb-1 of proton–proton collisions, collected with the ATLAS ......
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, ...
Can the halo model describe 2nd- and 3rd-order correlation functions of gravitational lensing consistently?
(2019-11-07)
To understand and model the distribution of and the relation between baryonic and dark matter in the Universe is one of the key challenges in contemporary astrophysics. A well-established theoretical description is given ......
Bestimmung der Doppelpolarisationsobservablen E in der Reaktion γ⃗p⃗ → pη am CBELSA/TAPS-Experiment in Bonn
(2019-03-07)
Photoproduktionsdaten beeinflussen zunehmend unser Bild der tatsächlich in der Natur existierenden Baryon-Resonanzen. Die Analyse von (Polarisations-)Observablen ist entscheidend für die Extraktion von Resonanzen aus diesen ......
Search for the Higgs Boson Decay into Bottom and Charm Quarks Using Proton-Proton Collisions at √s = 13 TeV
(2019-02-05)
A search for the Standard Model (SM) Higgs boson, produced in association with a Z boson, in decays to bottom or charm quarks is presented. The SM Higgs boson mass is assumed to be 125 GeV. These searches analyse a data ...
A dark matter quest through decaying axinos and vector-like portals
(2019-01-24)
To date there is no definite particle physics interpretation of dark matter. At the same time, LHC searches at √s = 14 TeV yielded no signals of physics beyond the Standard Model. Minimal models of new physics that predict ...
