  1. 1. ATLAS Calorimetry : Hadronic Calibration Studies

    Författare :Karl-Johan Grahn; Bengt Lund-Jensen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : The ATLAS experiment -- situated at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) in Geneva -- is on schedule to take its first collision data in 2009. Physics topics include finding the Higgs boson, heavy quark physics, and looking for extensions of the standard model such as supersymmetry. LÄS MER

  3. 2. Theoretical Studies of Hadronic Reactions with Vector Mesons

    Författare :Carla Terschlüsen; Stefan Leupold; Stefan Scherer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Vector mesons; Effective field theories; Chiral Lagrangian; Meson-meson interactionss; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

    Sammanfattning : Aiming at a systematic inclusion of pseudoscalar and vector mesons as active degrees of freedom in an effective Lagrangian, studies have been performed in this thesis concerning the foundations of such an effective Lagrangian as well as tree-level and beyond-tree-level calculations. Hereby, vector mesons are described by antisymmetric tensor fields. LÄS MER

  4. 3. Geant4 Monte Carlo Simulations of the International Space Station Radiation Environment

    Författare :Tore Ersmark; Bengt Lund-Jensen; Lembit Sihver; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Space physics; Rymdfysik;

    Sammanfattning : A detailed characterization of the proton and neutron induced radiation environment onboard Columbus and the International Space Station (ISS) has been carried out using the Geant4 Monte Carlo particle transport toolkit. Dose and dose equivalent rates, as well as penetrating particle spectra corresponding to incident trapped protons, GCR protons, SPE protons and cosmic ray albedo neutrons are presented. LÄS MER
