  1. 21. In-medium width of the η' meson

    Master-uppsats, Kärnfysik

    Författare :Carl Niblaeus; [2013]
    Nyckelord :Eta prime meson; width; finite temperature; lifetime; QCD; chiral perturbation theory; Eta prime meson; vidd; ändlig temperatur; livstid; QCD; kiral störningsteori;

    Sammanfattning : In this master’s thesis the width of the  meson is studied as a function of temperature. We consider a background medium consisting of a pion gas and assume a vanishing net baryon chemical potential. LÄS MER

  3. 22. Vector Meson Masses in AdS/QCD

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Douglas Svensson Seth; [2013]
    Nyckelord :Theoretical particle physics; anti-de Sitter space; quantum chromodynamics; meson masses; Witten diagrams.; Physics and Astronomy;

    Sammanfattning : We study the anti-de Sitter/conformal field theory correspondence (AdS/CFT correspondence) and investigate in a scalar model how n point functions can be calculated through functional derivatives and how they can be obtained with the use of Witten diagrams instead. We also study a previous anti-de Sitter/quantum chromodynamics (AdS/QCD) model where the mass of the phi meson has not been considered. LÄS MER
