1. Quark Distributions and Charged Higgs Boson Production : Studies of Proton Structure and New Physics
Sammanfattning : The Standard Model describes all elementary particles known today, but at larger energies it will have to be complemented with new particles and interactions. To be able to distinguish new physics at proton colliders such as LHC at CERN, it is essential to have an appropriate description of the colliding protons and their interactions. LÄS MER
2. Top Quark Pair Production in ATLAS
Sammanfattning : The Large Hadron Collider (LHC) at the international particle physics laboratory CERN in Switzerland is currently the most powerful particle accelerator on earth. This thesis presents analyses of proton-proton collisions at the energy √s = 7 TeV, recorded by ATLAS, one of the detectors at the LHC. LÄS MER
3. Quark and lepton interactions : studies of quantum chromo dynamics and Majorana neutrinos
Sammanfattning : .... LÄS MER
4. Calibration of the ATLAS calorimeters and discovery potential for massive top quark resonances at the LHC
Sammanfattning : ATLAS is a multi-purpose detector which has recently started to take data at the LHC at CERN. This thesis describes the tests and calibrations of the central calorimeters of ATLAS and outlines a search for heavy top quark pair resonances. LÄS MER
5. Top-Quark and Charged Higgs Boson Production at Hadron Colliders : Data Analysis at the DØ Experiment and Simulations for the ATLAS Detector
Sammanfattning : This thesis treats two different projects, both aiming at experimental tests at hadron colliders of some specific predictions of the Standard Model (SM) of particle physics and of its Minimal Supersymmetric extension (MSSM). The thesis is based on four papers. LÄS MER
