    Sammanfattning : The five different K -> 3 Pi and the three K -> 2 Pi decays are calculated in Chiral Perturbation Theory. The calculation is done using different approximations, to study whether this changes the result significantly. First the isospin approximation is used. Discrepancies are then found between theory and experiment. LÄS MER

  4. 8. Meson Decay with Isospin Breaking At Two Loops

    Författare :Karim Ghorbani; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kvantfältteori; Elementarpartikelfysik; quantum field theory; Elementary particle physics; Naturvetenskap; Natural science; hadron physics; standard model; chiral Lagrangian; quantum correction;

    Sammanfattning : In all calculations done in this thesis, the evaluation of higher order quantum corrections has been central. In the first paper included in this thesis we have investigated the effects of finite volume meson propagators for quark-antiquark vacuum expectation value at two-loop level. LÄS MER

  5. 9. B-physics potential of the ATLAS experiment and performance of the ATLAS Transition Radiation Tracker

    Författare :Chafik Driouichi; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; B-physics; LHC; Bc meson; Elementary particle physics; Transition Radiation Tracker; quantum field theory; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2004:Driouichi;

    Sammanfattning : The ATLAS experiment is one of the four experiments at the Large Hadron Collider (LHC), which is supposed to be operational in early 2007. Proton-proton collisions at an unprecedented center-of-mass energy of 14 TeV will probe new frontiers of the universe, hopefully providing a better understanding of the laws governing our universe.
