Study of a Light Standard Model Higgs Boson in the t¯tH0 Channel with ATLAS at LHC and Decay-Mode Independent Searches for Neutral Higgs Bosons with OPAL at LEP
(2004)
The production of a light Standard Model Higgs boson in association with a top-quark pair at the LHC is studied in a simulation of the ATLAS detector. The Higgs boson is assumed to decay into bb, and the top-quark pair to ......
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 $Z$ ...
Determination of Supersymmetric Parameters with Neural Networks at the Large Hadron Collider
(2013-12-20)
The LHC is running and in the near future potentially some signs of new physics are measured. In this thesis it is assumed that the underlying theory of such a signal would be identified and that it is some kind of minimal ...
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 ...
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, ...
Higgs Couplings and Supersymmetry in the Light of early LHC Results
(2014-08-04)
We present phenomenological studies investigating the implications of early results from the Large Hadron Collider (LHC) for models beyond the Standard Model (BSM), mostly focusing on Supersymmetry (SUSY). Our work covers ...
Search for the associated production of a W boson and a top quark with the ATLAS detector at 7 TeV
(2015-06-03)
An analysis searching for the associated production of a W boson and a top quark based on 4.7 fb-1 proton collision data recorded by the ATLAS detector at the LHC in 2011 at a centre-of-mass energy of √s ...
Evidence for the Higgs Boson Decay to t+t- in the Lepton + Hadrons Final State with ATLAS
(2015-03-12)
The data recorded with the ATLAS experiment during the first run period of the Large Hadron Collider are analysed by selecting final states with two τ-leptons, which further decay to a lighter lepton and to hadrons, ...
W → τντ Cross Section Measurement and Search for the Standard Model Higgs Boson in the τlep τhad Final State with the ATLAS Detector
(2015-03-13)
Two measurements based on proton-proton collisions recorded with the ATLAS experiment at the LHC with τ leptons and missing transverse energy in the final state are presented.

Measurement of the Associated Production of a Single Top Quark and a W Boson in Single-Lepton Events with the ATLAS Detector
(2016-06-10)
The production of a single top quark in association with a W boson (Wt) is measured with the ATLAS detector using proton-proton collision events with one lepton, three jets and missing transverse energy at √s = 8 TeV. ...
