Sarah Goes Left and Right Looking Beyond the Standard Model and Meets Susy
(2017-09-12)
Progress in the search for physics beyond the Standard Model (BSM) proceeds through two main avenues. The frst requires the development of models that address the host of theoretical and experimental deficiencies of the ...
Analyse komplexer dynamischer Systeme durch Charakterisierung retardierter, gerichteter und gewichteter Interaktionen
(2017-11-27)
Die Erforschung der Dynamik ausgedehnter komplexer Systeme stellt seit jeher eine der großen Herausforderungen in verschiedenen Bereichen der Wissenschaft dar, von Physik, über Informatik, Biologie, Geowissenschaften und ...
Production and PAC studies of 83Rb/83mKr solid state calibration sources for the KATRIN experiment
(2017-12-13)
The KATRIN experiment studies the tritium beta-decay kinematics to deduce the neutrino mass. The emitted electrons' kinetic energy close to the beta-spectrum's endpoint is analysed using a high-precision Magnetic Adiabatic ...
Search for Flavour Changing Neutral Currents through Single Top-Quark Production at √s= 8 TeV with the ATLAS Detector
(2017-12-20)
Flavour changing neutral current processes are highly suppressed in the Standard Model due to the Glashow-Iliopoulos-Maiani mechanism. However, many extensions of the Standard Model predict the existence of these processes ......
Topics in chiral perturbation theory for charmed mesons
(2017-10-10)
This thesis is concerned with topics in chiral perturbation theory for pseudoscalar charmed mesons in a manifestly Lorentz-invariant way. After constructing the chiral effective Lagrangian describing spinless matter fields ...
Exploring exotic states with twisted boundary conditions
(2017-10-24)
The goal of this thesis is to develop methods to study the nature and properties of exotic hadrons from lattice simulations. The main focus lies in the application of twisted boundary conditions. The thesis consists of a ...
Zeitaufgelöste Femtosekunden-Infrarotspektroskopie an einem Ferracyclobutadien zur Aufklärung des ultraschnellen photoinduzierten Ligandenaustauschs
(2017-04-19)
Diese Arbeit hat es sich zum Ziel gesetzt, die ultraschnellen Primärprozesse nach der optischen Anregung des Tricarbonyl-Ferracyclobutadien-Komplexes [Fe{κ2-C3(NEt2)3}(CO) ...
Measurement of Double Polarization Observables in the Reactions γp → pπ0 and γp → pη with the Crystal Barrel/TAPS Experiment at ELSA
(2017-10-10)
One of the remaining challenges within the standard model of particle physics is to gain a good understanding of QCD in the non-perturbative regime. A key step toward this aim is to obtain further insight into the structure ...
Studies of ω Photoproduction off Proton at the BGO-OD Experiment
(2017-09-21)
Hadrons are composite particles which experience a mutual, non-fundamental interaction, i.e. the same force responsible for keeping protons and neutrons bound together within the atomic nucleus. This hadronic interaction ...
Organization and function of signaling molecules in sperm
(2017-09-15)
Successful fertilization depends on the ability of sperm to locate the egg. Sperm from different species rely on diverse signaling components to gather chemical and physical cues and transduce them into a behavioral swimming ......
Um die Eizelle zu befruchten, müssen die Spermien die Eizelle zunächst lokalisieren. Dabei helfen ihnen unterschiedliche chemische oder physikalische Signale auf dem Weg zur Eizelle, die dann das Schwimmverhalten der ......
