1. 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
2. Phenomenology of Inert Scalar and Supersymmetric Dark Matter
Sammanfattning : While the dark matter has so far only revealed itself through the gravitational influence it exerts on its surroundings, there are good reasons to believe it is made up by WIMPs – a hypothetical class of heavy elementary particles not encompassed by the Standard Model of particle physics. The Inert Doublet Model constitutes a simple extension of the Standard Model Higgs sector. LÄS MER
3. Phenomenology of neutrino properties, unification, and Higgs couplings beyond the Standard Model
Sammanfattning : The vast majority of experiments in particle physics can be described by the Standard Model of particle physics (SM). However, there are indications for physics beyond it. The only experimentally demonstrated problem of the model is the difficulty to describe neutrino masses and leptonic mixing. LÄS MER
4. Experimental studies of particle production in ultra-relativistic heavy ion collisions
Sammanfattning : This thesis is about high energy heavy ion physics. Two major experiments, the WA98 at CERN and the PHENIX at Brookhaven National Laboratory, are described. Results from data analysis from both experiments are presented. The WA98 chapter presents particle identification methods and phi-meson measurements. LÄS MER
5. Experimental Studies of the Interaction of Atmospheric Aerosol Particles with Clouds and Fogs
Sammanfattning : In this work, cloud and fog droplet formation was studied in three joint field experiments. The instrument, the droplet aerosol analyser (DAA), has also been further developed and verified as part of this work. The DAA is an instrument especially developed for studies of cloud and fog droplet formation and growth. LÄS MER
