1. Looking for the Charged Higgs Boson : Simulation Studies for the ATLAS Experiment
Sammanfattning : The discovery of a charged Higgs boson (H+) would be an unambiguous sign of physics beyond the Standard Model. This thesis describes preparations for the H+ search with the ATLAS experiment at the Large Hadron Collider at CERN. The H+ discovery potential is evaluated, and tools for H+ searches are developed and refined. LÄS MER
2. 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
3. Luminosity determination and simulation of the LUCID detector at the ATLAS experiment
Sammanfattning : The aim of this thesis is to describe how the luminosity can be measured in the ATLAS experiment at the Large Hadron Collider. Luminosity is a fundamental quantity that is used in most physics studies at the LHC. For example in order to measure cross sections. LÄS MER
4. Searches for exotic stable massive particles with the ATLAS experiment
Sammanfattning : This thesis presents two signature-based searches for exotic long-lived particles using experimental data collected by the ATLAS experiment at the Large Hadron Collider (LHC) at CERN. At the LHC, proton-proton collisions take place at the world-record center-of-mass energy of 7 TeV and luminosities of up to 3×1033 cm-2s-1 . LÄS MER
5. Constraining the top-Z coupling using the (ttWj)EW process with the ATLAS experiment : A search for physics beyond the Standard Model
Sammanfattning : The Standard Model (SM) of particle physics, having been confirmed by numerous experiments, is one of the most successful theories in physics. It describes all known elementary particles and their interactions through the electromagnetic, strong and weak force. LÄS MER
