6. Search for Pair-Produced Supersymmetric Top Quark Partners with the ATLAS Experiment
Sammanfattning : Searches for the supersymmetric partner of the top quark (stop) are motivated by natural supersymmetry, where the stop has to be light to cancel the large radiative corrections to the Higgs boson mass. This thesis presents three different searches for the stop at √s = 8 TeV and √s = 13 TeV using data from the ATLAS experiment at CERN’s Large Hadron Collider. LÄS MER
7. Search for Weakly Produced Supersymmetric Particles in the ATLAS Experiment
Sammanfattning : The Large Hadron Collider located at CERN is currently the most powerful particle accelerator and ATLAS is an experiment designed to exploit the high energy proton-proton collisions provided by the LHC. It opens a unique window to search for new physics at very high energy, such as supersymmetry, a postulated symmetry between fermions and bosons. LÄS MER
8. First Determination of the Electric Charge of the Top Quark and Studies of the Top Quark Pair Background to New Physics
Sammanfattning : This thesis is concerned with experimental investigations of properties of the top quark and processes involving this particle. In the first part of the thesis, the first determination of the electric charge of the top quark is presented. LÄS MER
9. The search for a standard model Higgs at the LHC and electron identification using transition radiation in the ATLAS tracker
Sammanfattning : The Large Hadron Collider (LHC) will be ready for proton-proton collisions in the year 2005 and the ATLAS detector will be one of the two experiments at the LHC which will explore a new and higher energy range for particle physics. In this thesis, an analysis of the power of the ATLAS detector to detect a Standard Model Higgs boson has been performed. LÄS MER
10. Search for Charginos and Sleptons in ATLAS and Identification of Pile-up with the Tile Calorimeter
Sammanfattning : The standard model of particle physics (SM) describes the elementary particles and their interactions. Supersymmetry (SUSY), a symmetry beyond those included in the standard model could resolve some of the SM shortcomings. It can provide a candidate for Dark Matter and a solution to the hierarchy problem. LÄS MER
