Search for Supersymmetry and kinematic endpoint measurement in final states with two tau leptons with the ATLAS detector at the LHC
(2011-10-21)
Discovery prospects for Supersymmetry in final states with at least two tau leptons and large missing transverse energy are evaluated for LHC proton-proton collisions measured with the ATLAS detector. In a first study based ......

Search for Supersymmetry with Hadronically and Leptonically Decaying Tau Leptons at the ATLAS Experiment
(2017-01-20)
The search for physics beyond the Standard Model (SM) is a central focus of modern particle physics. Supersymmetric extensions (SUSY) to the SM offer elegant solutions to many unresolved questions of the theory. This thesis ...
Identification of hadronic τ decays using the τ lepton flight path and reconstruction and identification of jets with a low transverse energy at intermediate luminosities with an application to the search for the Higgs boson in vector boson fusion with the ATLAS experiment at the LHC
(2010-07-01)
Three studies of different components of the object reconstruction with the ATLAS experiment using simulated data are presented. In each study, a method for the improvement of the reconstruction is developed and the ...

Search for the H → bb Decay of the Standard Model Higgs Boson in Associated Production with Vector Bosons Using ATLAS Data at √s = 8 TeV
(2018-10-29)
In this thesis, a search for the H → bb decay of the Standard Model Higgs boson is presented. A dataset of 20.2 fb-1 recorded by the ATLAS detector at CERN is ......
Measurement of the Weak Mixing Angle and the Spin of the Gluon from Angular Distributions in the Reaction pp → Z/γ* + X → μ+μ- + X with ATLAS
(2013-11-15)
The measurement of the effective weak mixing angle with the ATLAS experiment at the LHC is presented. It is extracted from the forward--backward asymmetry in the polar angle distribution of the muons originating from $Z$ ...
Measurement of the top-quark mass and the ttZ cross section in ATLAS: the tt dilepton way
(2015-07-07)
A measurement of the top-quark mass and the ttZ cross section is performed using 4.6 fb-1 and 20.3 fb-1 of data from proton-proton collisions collected ...
Observation of W → τντ Decays with the ATLAS Experiment
(2011-05-04)
Physics studies of processes with t leptons in the final state, while challenging at hadron colliders, are of great importance at the LHC. The τ leptons provide important signatures in searches for the Higgs boson as well ......
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 ...
Study of top-quark pair cross-section measurement in the dilepton channel with the ATLAS detector at the LHC
(2011-09-16)
The top quark is the heaviest of the known fundamental particles in the Standard Model (SM) with a mass of 173.3±1.1GeV. It is the sixth quark in the SM and the weak isospin partner of the bottom quark. Properties such as ......
