On Different Parametrizations of Feynman Integrals
… one hand, allow us to compute cross sections and differential distributions at high precision and, on the other hand, give us deep mathematical insights on the mathematical structures of Feynman integrals.</p> <p>We start by presenting phenomenological calculations relevant for the experimental …

Measurement of top-antitop differential cross sections in the di-lepton channel with ATLAS in p-p collisions at 7TeV
This dissertation presents a measurement of differential cross sections as a function of mass, transverse momentum and rapidity of the top quark pairs using $\sqrt{s} = 7 \TeV$ proton-proton collision data collected by the ATLAS detector at the Large Hadron Collider. This data corresponds to an …

Measurement and QCD analysis of event shape variables in deep-ineleastic electron-proton collisions at HERA
… luminosity of 106 pb^-1 are used to study the differential distributions of event shape variables. These include two-jet event shapes (thrust, jet broadening, jet mass and the C-parameter), as well as three-jet event shapes (out-of-event-plane momentum and azimuthal correlation) and jet rates. …

Observations and measurement of W boson production and triple gauge couplings at LEP II
… sections of these W production processes and the differential distributions of the event shapes are then used to measure the couplings of Wbosons with Z bosons and photons. Emphasis is placed on the unambiguous and efficient combination of the information from the different production and decay …

Investigation of Exclusive Photoproduction of eta-rho0 and pi0-rho0 Meson Pairs at HERA
… is made to explain this process but the measured differential distributions are consistent with a contribution from Pomeron exchange.\\ In the analysis of photoproduced $\pin-\rho^{0}$ meson pairs no significant $\rho$ meson signal can be extracted. % the signal of the $\rho^{0}$ meson can not …

Consequences of drought, flooding, and insect herbivory on the distributions of closely related willow and poplar (Salicaceae) species across hydrologic gradients in Minnesota wetlands
… affect beta diversity, if biotic factors exert differential effects on species performances across environmental gradients. Contributions of different community assembly processes to beta diversity can be tested with multiple approaches. First, experimental approaches allow direct tests of …

The Development of Computational Tools for Theoretical Predictions in Particle Physics at the Large Hadron Collider
The Large Hadron Collider (LHC) experiments are an excellent tool for the improvement of our knowledge of the Standard Model and the examination of Beyond Standard Model theories. Nonetheless, to maximise the learning-potential of the LHC, clear and precise theoretical predictions are needed, for …
