  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. Analysis of the phase space, asymptotic behavior and stability for heavy symmetric top and tippe top

    Author : Markus Sköldstam; Stefan Rauch-Wojciechowski; Torkel Glad; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; symmetric top; tippe top; vertical rotation; truncated sphere; asymptotic trajectories; MATHEMATICS; MATEMATIK;

    Abstract : In this thesis we analyze the phase of the heavy symmetric top and the tippe top. These tops are two examples of physical systems for which the usefulness of integrals of motion and invariant manifolds, in phase space picture analysis, can be illustratedIn the case of the heavy symmetric top, simplified proofs of stability of the vertical rotation have been perpetuated by successive textbooks during the last century.

  5. 3. First Determination of the Electric Charge of the Top Quark and Studies of the Top Quark Pair Background to New Physics

    Author : Per Hansson; Bengt Lund-Jensen; Jorgen D'Hondt; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; experimental particle physics; particle physics; standard model tests; dzero; fermilab; tevatron; top quark; top physics; electric charge; atlas; cern; lhc; large hadron collider; supersymmetry; Elementary particle physics; Elementarpartikelfysik; Physics; Fysik;

    Abstract : 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. READ MORE

  6. 4. Top Quark Pair Production in ATLAS

    Author : Karl Gellerstedt; Jörgen Sjölin; Kerstin Jon-And; Cecilia Gerber; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; particle physics; top quark; LHC; ATLAS; fysik; Physics;

    Abstract : 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. READ MORE

  7. 5. The bottom line of cultural diversity at the top : the top management team's cultural diversity and its influence on organisational outcomes

    Author : Timurs Umans; Sven-Olof Collin; Rikard Larsson; Håkan Pihl; Eva M. Meyersson Milgrom; Företagsekonomiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; organisational outcome; Top management team; cultural diversity; Företagsekonomi; Business administration; Top management team; organisational outcome; cultural diversity;

    Abstract : This dissertation investigates the relationship between cultural diversity in top management team (TMT) and organisational outcomes. The theoretical framework developed within this dissertation identifies three major concerns in this relationship. READ MORE
