2. 1. Top Quarks at the Tevatron : Measurements of the Top Quark Production and Decay with the D0 Experiment

   Author : Jonas Strandberg; Barbro Åsman; Michael Albrow; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; elementary particle physics; D0; Tevatron; top quark; Physics; Fysik;

   Abstract : This thesis presents two measurements of the top quark using 230 pb-1 of data taken with the D0 detector at the Tevatron accelerator. The first measurement determines the top pair production cross section at sqrt(s)=1.96 TeV in proton-antiproton collisions. READ MORE

4. 2. Measurements of Angular Correlations in Minimum Bias Events and Preparatory Studies for Charged Higgs Boson Searches at the Tevatron and the LHC

   Author : Camille Bélanger-Champagne; Claus Buszello; Tord Ekelöf; Nick van Remortel; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ATLAS; D0; LHC; Tevatron; CERN; Fermilab; QCD; Monte Carlo tunes; Matrix Element method; Charged Higgs boson; Tau lepton; Trigger; Physics; Fysik; Elementary particle physics; Elementarpartikelfysik; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

   Abstract : Studies of minimum bias events at colliders probe the behavior of QCD in the non-perturbative regime. The phenomenology of events in this regime is described by empirical models that take many parameters, which all need to be tuned to the observed data. READ MORE

5. 3. Top-Quark and Charged Higgs Boson Production at Hadron Colliders : Data Analysis at the DØ Experiment and Simulations for the ATLAS Detector

   Author : Nils Gollub; Tord Ekelöf; Richard Brenner; Patrizia Azzi; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; ATLAS; LHC; charged Higgs boson; MSSM; D0; Tevatron; top quark; elementary particle physics; Elementarpartikelfysik; Elementary particle physics; Elementarpartikelfysik;

   Abstract : 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. READ MORE

6. 4. High pressure structural investigations using single crystal techniques : influence of pressure on Jahn-Teller distorted alkali manganese fluorides

   Author : Stefan Carlson; Stefan Werner; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; strukturkemi; Structural Chemistry;

   Abstract : The results from high-pressure single-crystal X-ray diffraction studies of some ternary sodium transition metal fluorides are presented. The structures of NaMnF4, Na2MnF5, Na3MnF6 and Na3ScF6 have been investigated at high pressures, and in connection with these studies the Na5Mn3F14 structure has been investigated at ambient pressure.

7. 5. Outcome of gastric cancer surgery in Sweden

   Author : Chih-Han Kung; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Gastric cancer worldwide is the fifth most common cancer and has the third highest cancer related mortality. Curative treatment includes surgical resection but comes with risk of complications and the optimal surgery including extent of lymphadenectomy has evolved over time. READ MORE
