  1. 1. Phenomenological Studies on Supersymmetry and the Strong Force

    Författare :Peter Skands; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :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

  3. 2. Necked-in Superdeformed Nuclei

    Författare :Lars-Ove Jönsson; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; thermodynamics; statistical physics; gravitation; cranked Nilsson-Strutinsky; superdeformation; necked-in shapes; RPA; giant dipole resonance; finite-range liquid drop model; Mathematical and general theoretical physics; classical mechanics; relativity; quantum mechanics; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:1997:Jönsson;

    Sammanfattning : Superdeformation, i.e. elongated shapes with the longest axis approximately twice as long as the shorter axes, has provided many new insights in nuclear structure. In this dissertation the possibility of forming superdeformed states related to two connected spheres, having a more or less pronounced neck, is investigated. LÄS MER

  4. 3. Quantum Chaos and Dissipation in Finite Fermi Systems

    Författare :Sergiy Radionov; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; Mathematical and general theoretical physics; classical mechanics; quantum mechanics; Dissipation; Quantum Chaos; Collective motion; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik;

    Sammanfattning : We address the problem of the dissipative character of collective motion in finite Fermi systems. We study this problem from the point of view of chaotic features of the fermionic degrees of freedom of the many-body Fermi systems. LÄS MER

  5. 4. Correlations in multiparticle production

    Författare :Markus Ringnér; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; String fragmentation; QCD; Correlations; Colour interference; Bose-Einstein interference; quantum mechanics; classical mechanics; Mathematical and general theoretical physics; relativity; gravitation; statistical physics; Matematisk och allmän teoretisk fysik; High energy interactions; thermodynamics; kvantmekanik; klassisk mekanik; termodynamik; cosmic rays; Kosmisk strålning; högenergi; statistisk fysik; relativitet; Fysicumarkivet A:1998:Ringnér;

    Sammanfattning : Different aspects of the strong interaction in particle collisions are studied. Most of the work is based on the Lund string fragmentation model for hadron production. A model which incorporates interference between identical bosons in the string model is presented. LÄS MER

  7. 5. Hadronization Effects in the Strong Interaction

    Författare :Patrik Edén; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; Mathematical and general theoretical physics; classical mechanics; quantum mechanics; string fragmentation; baryon production; jets; QCD; hadronization; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; High energy interactions; cosmic rays; Kosmisk strålning; högenergi;

    Sammanfattning : Different hadronization effects in high energy interactions are investigated. The frame-work is the Lund model for the strong interaction. A model for baryon production in jet fragmentation is presented and extended to baryon remnant fragmentation in deep inelastic scattering and hadron--hadron collisions. LÄS MER
