Measurements of differential t-channel single top-quark production cross-sections in proton–proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS detector
(2018-03-28)
Proton-proton collision data at a centre-of-mass energy of 8 TeV recorded with the ATLAS detector in 2012, corresponding to an integrated luminosity of 20.2 fb-1, are used to measure absolute and normalised ...
Investigations into the DNP characteristics of electron and proton irradiated polyethylene and polypropylene
(2018-03-06)
To achieve a significant enhancement of the nuclear polarisation of solid state target materials one must use the method of dynamic nuclear polarisation. This necessitates unpaired electrons, that can be created as ...
Modulation Spectroscopy of Ultracold Atoms in Optical Lattices
(2018-03-12)
In the past fifteen years ultracold atoms confined to optical lattices, which are artificial crystals of light, have proven to be powerful tools in the study of strongly correlated many-body systems widely known from a ......
Probing the top-quark coupling to the photon through the cross-section measurement of ttγ production in pp collisions with the ATLAS detector
(2018-07-03)
The cross section of top-quark pair production in association with a photon is measured in proton-proton collisions at a centre-of-mass energy of 8 TeV with 20.2 fb-1 of data and at 13 TeV with 36.1 fb-1 ...
Variable Potentiale für thermisches Licht und gekoppelte Photonenkondensate
(2018-01-16)
Seit mehr als einer Dekade lassen sich mit ultrakalten Atomen in periodischen Gitterpotentialen viele Aspekte der Festkörperphysik an sehr reinen, künstlichen Kristallen studieren. So konnte beispielsweise der Übergang von ...
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 ...
