  1. 1. Aspects of the Duality between Supersymmetric Yang-Mills Theory and String Theory

    Författare :Daniel Bundzik; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; classical mechanics; quantum mechanics; relativity; gravitation; statistical physics; thermodynamics; Natural science; Naturvetenskap; Physics; Fysik; Mathematical and general theoretical physics; Star product; Leigh-Strassler deformation; R-matrix; Integrability; Spin-chains; Fractional D-branes; type IIB string theory; AdS CFT-correspondence; gauge gravity correspondence; kvantmekanik; klassisk mekanik; termodynamik; statistisk fysik; relativitet;

    Sammanfattning : This thesis deals with three topics related to the Ads/CFT correspondence. In Paper I, solutions describing the geometry of fractional D1-branes of Type IIB string theory are presented. The running coupling constant is computed on the gauge theory side. LÄS MER

  3. 2. Meson Properties in Partially Quenched Effective Field Theory

    Författare :Niclas Danielsson; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; quantum mechanics; classical mechanics; Mathematical and general theoretical physics; Fysik; Chiral Perturbation Theory; masses; decay constants; Physics; electromagnetic interactions; Strong interactions; pseudoscalar mesons; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik;

    Sammanfattning : Mass corrections and decay constants for light mesons have been calculated in Partially Quenched Chiral Perturbation Theory. The calculations of the charged meson masses have been performed to third order, first for degenerate quark masses, and then, in a second project, for the general case. LÄS MER

  4. 3. Structure of Deformed Proton-rich Nuclei Studied by Beta-decay

    Författare :Petter Urkedal; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical and general theoretical physics; classical mechanics; relativity; quantum mechanics; termodynamik; statistisk fysik; relativitet; kvantmekanik; klassisk mekanik; Matematisk och allmän teoretisk fysik; thermodynamics; gravitation; statistical physics; Physics; nuclear-structure beta-decay proton-rich drip-line neutrino; Fysik; Fysicumarkivet A:2002:Urkedal;

    Sammanfattning : Nuclear structure is studied using beta-decay reactions as a probe and focusing on medium-heavy proton-rich nuclei. One of the included articles is a systematic study covering a major part of the nuclear chart, especially searching for nuclei which may be sensitive to sub-MeV neutrinos... LÄS MER

  5. 4. Fundamental properties of neutrinos: masses and mixings

    Författare :Solveig Skadhauge; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; Fysik; Physics; quantum mechanics; classical mechanics; Mathematical and general theoretical physics; statistical physics; gravitation; relativity; statistisk fysik; termodynamik; thermodynamics; klassisk mekanik; kvantmekanik; relativitet; Fysicumarkivet A:2002:Skadhauge;

    Sammanfattning : Neutrino physics is one of the fastest growing topic in phenomenological high energy physics. Neutrinos are elementary neutral particles and participate only in the weak interactions. For this reason it is very difficult to detect them experimentally. Nevertheless, much experimental progress has been obtained in the recent years. LÄS MER
