Das Datenerfassungssystem für das Crystal-Barrel/TAPS-Experiment an ELSA
(2019-04-30)
Die Hadronenspektroskopie untersucht die Kräfte zwischen den Quarks in Hadronen. Dazu werden die Anregungsspektren der Hadronen untersucht und mit Modellen, wie zum Beispiel Konstituenten-Quarkmodellen, oder Gitter-QCD ...
Inclusive and differential cross-section measurements of tW single top-quark production at √s = 13 TeV with the ATLAS detector
(2019-06-27)
This thesis presents the inclusive cross-section measurement and so far the first differential cross-section measurement for the associated production of a top quark and a W boson, known as the tW-channel, at 13TeV. The ...
Search for charged lepton-flavour violation in top-quark decays at the LHC with the ATLAS detector
(2019-09-06)
A direct search for charged lepton-flavour violation in top-quark decays is presented. The data analysed correspond to 79.8 fb-1 of proton-proton collisions at a centre-of-mass energy of √s = 13 TeV delivered ......
Development of depleted monolithic active pixel sensors for high rate and high radiation experiments at HL-LHC
(2019-07-10)
Depleted monolithic active pixel sensors (DMAPS) are developed to demonstrate their suitability for high energy particle physics experiments in high radiation and high hit-rate environments. In this thesis, characterization ...
Dynamics of Open Quantum Systems
(2019-06-13)
Remarkable experimental progress and theoretical advancements in the study of strongly corre- lated systems have opened up new doors towards a better understanding of interesting states of matter. Such states could possibly ...
High precision timing
(2019-04-30)
Pulsars are highly magnetised, fast spinning neutron stars, formed after a supernova explosion. Pulsars have been used to study a wide range of physical and astrophysical phenomena. The majority of science that we can do ...
Storage of Short Light Pulses in a Fiber-Based Atom-Cavity System
(2019-05-16)
In this work I theoretically investigate and experimentally realize the storage of short light-pulses in a fiber-based atom-cavity system. Our miniaturized optical resonator - with seven times the natural atomic linewidth ...
Data Handling Processor and Signal Transmission in the Belle II DEPFET Pixel Detector
(2019-06-13)
The high precision measurements at the B factories have generated a new insight of the Standard Model with respect to CP violation and delivered higher constraints on the Standard Model parameters, i.e. CKM matrix. The ...
Optimal quantum control of atomic wave packets in optical lattices
(2019-05-24)
In this work, I investigate the motional control and the transport of single neutral atoms trapped in an optical conveyor belt. The main goal is to prepare the atoms in the vibrational ground state of the trapping potential ...
Analysis of inclusive semileptonic B meson decays with τ lepton final states at the Belle experiment
(2018-06-15)
In this thesis, the measurement of the inclusive branching fraction of B→Xτν decays at the Belle experiment is presented. Previous measurements of the inclusive semileptonic b-hadron branching fraction BR(b→Xτν) in ...
