Low mass hybrid pixel detectors for the high luminosity LHC upgrade
(2013-11-11)
Reducing material in silicon trackers is of major importance for a good overall detector performance, and poses severe challenges to the design of the tracking system. To match the low mass constraints for trackers in High ...
Detector Optimization Studies and Light Higgs Decay into Muons at CLIC
(2013-09-27)
The Compact Linear Collider (CLIC) is a concept for a future e+e- linear collider with a center-of-mass energy of up to 3 TeV. The design of a CLIC experiment is driven by the requirements related to ...
A GEM based Time Projection Chamber with pixel readout
(2013-09-04)
The large number of measured track points and the low material budget make a Time Projection Chamber (TPC) the ideal tracking device for particle flow optimized experiments. A highly segmented readout scheme, based on GEMs ...
A search for stable massive particles carrying electric charges in the range of 2e to 6e in proton-proton collisions at √s = 7 TeV recorded with the ATLAS detector at the LHC
(2013-09-02)
This dissertation presents a search for long-lived, multi-charged particles using the ATLAS detector at the LHC. Motivation for this search arose from an unexploited search regime at ATLAS of stable massive particles with ...
Ferromagnetic Semiconductor-Metal Transition in Heterostructures of Electron Doped Europium Monoxide
(2013-10-17)
In the present work, we develop and solve a self-consistent theory for the description of the simultaneous ferromagnetic semiconductor-metal transition in electron doped Europium monoxide. We investigate two different types ...
Untersuchung der Dynamik von Transportrezeptoren an der Kernpore mittels kontrastverstärkter Einzelmolekül-Fluoreszenzmikroskopie
(2013-09-17)
Der Austausch von Proteinen zwischen Zellkern und Zytoplasma findet für Proteine mit einer Masse größer als 40kDa durch den Kernporenkomplex statt. Import- und Exportfaktoren binden an Kernlokalisierungs- bzw. Kernexportsequenzen ...
Measurement of the transverse momentum distribution of Z bosons in proton-proton collisions at √s = 7TeV using the ATLAS detector
(2013-09-25)
Z boson production at the LHC presents a good opportunity to test Standard Model predictions. This thesis reports the measurement of the Z boson transverse momentum distribution in proton-proton collisions at sqrt(s)=7TeV, ...
Search for Flavour Changing Neutral Currents in Single Top-Quark Production at √s = 7 TeV with the ATLAS Detector
(2013-04-05)
This thesis represents the search for single top-quark production through flavour changing neutral currents using data collected by the ATLAS detector in 2011, at a centre-of-mass energy of √s = 7 TeV, corresponding to an ......
Search for MSSM Higgs Bosons in Di-τ Final States with the ATLAS Experiment
(2013-04-12)
A search for neutral MSSM Higgs bosons decaying into a τ lepton pair, A/H/h → τ+τ-, is presented. The search is based on proton?proton collision events recorded with the ATLAS detector at the Large ......
Domain Patterns and Dynamics in the Magnetoelectric Switching of Spin-Spiral Multiferroics
(2013-01-17)
The magnetoelectric effect has attracted tremendous attention in the past decade because it is highly interesting for applications. In particular, magnetoelectric switching allows to switch a magnetic order by an electric ...
