  1. 1. Physics at the High-Energy Frontier : Phenomenological Studies of Charged Higgs Bosons and Cosmic Neutrino Detection

    Författare :Oscar Stål; Gunnar Ingelman; Johan Rathsman; Jonathan Ellis; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; particle physics; Standard Model; beyond the Standard Model; supersymmetry; Higgs physics; charged Higgs boson; LHC; flavour physics; ultra-high-energy neutrinos; Askaryan effect; radio detection; lunar satellites; Elementary particle physics; Elementarpartikelfysik; högenergifysik; High Energy Physics;

    Sammanfattning : The Standard Model of particle physics successfully describes present collider data. Nevertheless, theoretical and cosmological results call for its extension. A softly broken supersymmetric completion around the TeV scale solves several of the outstanding issues. Supersymmetry requires two Higgs doublets, leading to five physical Higgs states. LÄS MER

  3. 2. Calibration of b-tagging and search for Dark Matter : Calibration of b-tagging efficiency and search for Dark Matter production in association with heavy flavour quarks with the ATLAS experiment

    Författare :Anna Shcherbakova; Sara Strandberg; Oscar Gonzalez Lopez; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ATLAS; ATLAS experiment; physics analysis; LHC; Large Hadron Collider; Dark Matter; b-tagging; fysik; Physics;

    Sammanfattning : The Large Hadron Collider (LHC) is the most powerful and complex particle accelerator ever built. The ATLAS and the CMS are the two multipurpose particle detectors at the LHC, designed to cover a wide range of physics measurements. LÄS MER

  4. 3. Phenomenological Studies on Supersymmetry and the Strong Force

    Författare :Peter Skands; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; R-parity violation; Physics; beam remnants; hadronisation; parton showers; underlying event; Supersymmetry; Fysik; QCD; Fysicumarkivet A:2004:Skands;

    Sammanfattning : In this thesis, we first consider the phenomenology of R-parity violating supersymmetric extensions of the Standard Model. Specifically, a large number of Lepton and Baryon Number violating decays of sparticles to particles are implemented in the Pythia event generator. LÄS MER

    Sammanfattning : The Large Hadron Collider (LHC) is the most powerful and complex particle accelerator ever built. The ATLAS detector is a general-purpose particle detector at the LHC, designed to cover a wide range of physics measurements. LÄS MER

  7. 5. Pion and Kaon Dynamics at Higher Orders in Chiral Perturbation Theory

    Författare :Pierre Dhonte; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; thermodynamics; statistical physics; gravitation; chiral perturbation theory; strong interactions; pseudo-scalar mesons; Mathematical and general theoretical physics; form factors; scattering; classical mechanics; relativity; quantum mechanics; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:2004:Dhonte;

    Sammanfattning : Higher orders calculations of processes involving the pion and kaon pseudo-scalar mesons are presented in the framework of three flavour Chiral Perturbation Theory. The purpose is two-fold. First determining the low energy constants of ChPT that are necessary for higher accuracy predictions. LÄS MER
