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 $Z$ ...
Multivariate methods and the search for single top-quark production in association with a W boson in ATLAS
(2013-05-28)
This thesis describes three machine learning algorithms that can be used for physics analyses. The first is a density estimator that was derived from the Green’s function identity of the Laplace operator and is capable of ......
Search for Supersymmetry with Tau Leptons, Muons, Missing Transverse Momentum and Jets with the ATLAS Experiment at the Large Hadron Collider
(2013-09-16)
Beyond the established Standard Model (SM), the search for new physics is among the most important ventures of modern physics. Supersymmetry (SUSY) is a natural candidate for an extension of the SM to account for unexplained ...
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 ...
