Diamond and Silicon Pixel Detectors in High Radiation Environments
(2012-10-24)
Diamond pixel detector is a promising candidate for tracking of collider experiments because of the good radiation tolerance of diamond. The diamond pixel detector must withstand the radiation damage from 10^{16} particles ...
Probing quark mass effects in low-energy hadron physics
(2012-12-21)
Since quarks are confined inside hadrons, their properties as well as their contributions to hadronic observables can be assessed by indirect methods only. As the strength of the strong interaction increases with the spatial ...
Implementation of a kinematic fit of single top-quark production in association with a W boson and its application in a neural-network-based analysis in ATLAS
(2012-09-05)
In order to provide discrimination between the Wt-channel signal and its backgrounds for analyses that try to measure single top-quark production in the Wt-channel, a kinematic fit to the lepton+jets decay ...
Supersymmetry Phenomenology in the Context of Neutrino Physics and the Large Hadron Collider LHC
(2012-09-17)
Experimentally, it is well established that the Standard Model of particle physics requires an extension to accommodate the neutrino oscillation data, which indicates that at least two neutrinos are massive and that two ...
Heterotic Particle Models from various Perspectives
(2012-10-24)
We consider the compactification of heterotic string theory on toroidal orbifolds and their resolutions. In the framework of gauged linear sigma models we develop realizations of such spaces, allowing to continously vary ...
Characterization of contaminated sites and monitoring of processes accompanying bioremediation using spectral induced polarization imaging
(2012-09-28)
Measurements of spectral induced polarization (SIP) provide information about the electrical conduction and polarization properties of the subsurface, and their frequency dependence. Several laboratory studies in the last ...
Single-top production t-channel cross section measurement in the electron+jets final state at ATLAS with 35 pb-1 of data
(2012-09-03)
The cross section of the Standard Model electroweak production of a single top quark in the t-channel has been measured using the LHC proton-proton collision data at $sqrt{s}=7$ TeV, $35 {\rm pb}^{-1}$ of integrated ...
Konstruktion und Erprobung eines intraoralen Belastungsgeräts zur Bestimmung von Kraft/Auslenkungszusammenhängen von Zähnen im menschlichen Gebiss
(2012-09-21)
Die Gingivitis und die Parodontitis haben meist eine schädigende Wirkung auf den Zahnhalteapparat und können die mechanischen Eigenschaften des Parodontalligaments (PDL) beeinflussen. Das Hauptziel dieser Studie war die ...
Inflation and Dark Matter Primordial Black Holes
(2012-09-26)
In this thesis a broad range of single field models of inflation are analyzed in light of all relevant recent cosmological data, checking whether they can lead to the formation of long--lived Primordial Black Holes (PBHs) ...
Design optimization of the ¯PANDA Micro-Vertex-Detector for high performance spectroscopy in the charm quark sector
(2011-09-01)
The ¯PANDA experiment is one of the key projects at the future FAIR facility, which is currently under construction at GSI Darmstadt. Measurements will be performed with antiprotons using a fixed-target setup. The main ...
