Dispersion-theoretical analysis of ππ and πη rescattering effects in strong three-body decays
(2021-10-08)
Employing dispersion theory to analyse hadronic three-body decays is a classic subject. Based on the fundamental physical principles of analyticity and unitarity, dispersion relations exploit basic theorems of complex ......
Bose-Einstein condensation of erbium atoms for fractional quantum Hall physics
(2021-04-21)
With the advent of ultracold atomic gases experimentally realized by laser cooling techniques nearly 40 years ago, the doors to accessing novel physical behaviour have been opened wide and far. Experimentally, research in ...
A 3-mm Imaging Line Survey of the Central Molecular Zones of M 82 and IC 342
(2020-07-07)
The central molecular zones of two nearby galaxies M 82 and IC 342 are among the most prominent extragalactic molecular sources in the northern hemisphere. While M 82 is a relatively small late type starburst galaxy, IC ...
Die Implementierung des Themas Fernerkundung in den Schulunterricht der Sekundarstufe I durch das neue MINT-Wahlpflichtfach "Geographie-Physik": eine Studie zur praktischen Schulfachgestaltung im Differenzierungsbereich der Jahrgangsstufen 8 und 9 an Gymnasien in Nordrhein-Westfalen am Beispiel des Gymnasiums Siegburg Alleestraße
(2021-10-26)
Schülerinnen und Schüler werden in ihrer Alltagswelt seit dem letzten Jahrzehnt immer früher mit Satellitenbildern konfrontiert. Durch den Wetterbericht und die Nachrichtensendung im Fernsehen oder durch virtuelle Globen ...
Optimierung der GEM-basierten Verstärkungsstufe einer TPC für das CB/TAPS-Experiment
(2020-08-10)
Das CB/TAPS-Experiment widmet sich der Untersuchung des Spektrums angeregter Hadronen. In seinem aktuellen Aufbau ist es dabei auf die Identifikation und der Vermessung ungeladener Endzustände spezialisiert. In einer ...
Indirect probes to constrain the CP nature of the Higgs boson
(2021-08-09)
The measurements of the coupling, spin, and charge-parity CP properties of the Higgs boson are consistent with the Standard Model (SM) predictions. However, the corresponding uncertainties are still large, and alternative ...
Probing the Standard Model of particle physics with ttH, WWZ and WZZ multilepton final states
(2020-01-13)
The Standard Model of particle physics elegantly describes the fundamental constituents of matter and their interactions. The electroweak gauge and top-quark Yukawa couplings can be directly probed in the associated ...
Probing new physics with boosted H → bb decays with the ATLAS detector at 13 TeV
(2020-01-27)
The discovery of the Higgs boson by the ATLAS and CMS collaborations at the Large Hadron Collider was a major success in particle physics. Even though studies of the Higgs boson suggest that its properties are in agreement ......
Nuclear Physics in a finite volume: Investigation of two-particle and α-cluster systems
(2021-01-25)
We investigate both analytically and numerically some artifacts introduced by the lattice environment in two-body charged fermion and antifermion systems and in α-conjugate nuclei. The finite (hyper)cubic lattice as a ...
Ramsey Imaging of Optical Dipole Traps: and its applications in building a 3D optical lattice
(2021-09-20)
In this work, I present the experimental realization of two-dimensional state-dependent transport of cesium atoms trapped in a three-dimensional optical lattice. Leveraging the ability to state-dependently transport atoms, ...
