Measurement of the Higgs Boson Decay to τ-Pairs in the Lepton plus Hadrons Final State in Proton-Proton Collisions with the ATLAS Detector
(2016-11-28)
In this thesis, the decay of the Standard Model Higgs boson into one hadronically and one leptonically decaying τ lepton is investigated using multivariate methods. Proton-proton collisions recorded by the ATLAS experiment ...
Precision Calculations in Supersymmetric Models using Phenomenological Tools
(2016-12-21)
We present a Higgs mass calculation at two-loop level based on the effective potential approach, which has been made available in the public computer codes SARAH and SPheno. The approach is based on generic formulae for ...
Kinematics study of M81 and M82 Galaxies
(2016-12-21)
The measurement of proper motion combined with the radial velocities, is an important tool for our understanding of the dynamics and evolution of galaxies in a group environment. One of the nearest group is the M$,$81 group ...
Design Studies for the Pixelized Readout of a TPC for the ILD
(2016-08-31)
A large Time Projection Chamber (TPC) is foreseen as central tracking device of the International Large Detector (ILD), as it provides a large number of measured track points simultaneously with a minimum of material budget. ...
Probing Gravity with High-Precision Pulsar Timing
(2016-12-22)
Pulsars are highly magnetised neutron stars which spin tremendously fast, at periods that are as low as a few milliseconds. Chapter 1 gives an overview of their basic observational properties and applications. Pulsars are ...
Fast non-destructive internal state detection of neutral atoms in optical potentials
(2016-11-29)
Neutral atoms trapped in optical lattices are promising candidates for quantum information processing and quantum simulation. Over the last decades, elegant tools for the manipulation of the internal and external states ...
Characterization of doping atoms (Ta, Nb) in advanced PEM fuel cell supports and catalysts as well as of the surface-solvent interaction of laser-generated Pt nanoparticles: A XAFS study
(2016-12-21)
PEM fuel cells are an interesting energy source for mobile applications. Efforts to improve their weaknesses cost, performance, and durability include improving the catalysts’ supports. Encouraging approaches are ...
Automatised Constraints on New Physics at the LHC and Beyond
(2016-10-28)
In this thesis, we discuss the development and use cases of the public software CheckMATE which is designed to allow for easy tests of theories beyond the Standard Model against current results from the Large Hadron Collider ...
Controlling surface plasmon polaritons with dielectric nanostructures
(2016-12-22)
This thesis focuses on the investigation of methods to control surface plasmon polaritons (SPPs), i.e., coupled oscillations of electromagnetic waves with the conduction band electrons at the surface of metals.
In ...

Envelope inflation in massive stars near the Eddington limit
(2016-12-21)
Massive stars, i.e. those stars with masses more than about 10 times that of the Sun, are important agents for the chemical and dynamical evolution of galaxies. Because of the steep mass-luminosity relation, massive stars ...
