  2. 16. Hadronization Effects in the Strong Interaction

    Author : Patrik Edén; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : 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;

    Abstract : 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. READ MORE

    Author : Hamid Kharraziha; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cosmic rays; event generators; colour factors; High energy interactions; hadronic jets; QCD; the Linked Dipole Chain model; quantum mechanics; relativity; gravitation; statistical physics; thermodynamics; Matematisk och allmän teoretisk fysik; kvantmekanik; klassisk mekanik; Kosmisk strålning; högenergi; classical mechanics; Mathematical and general theoretical physics; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:1997:Kharraziha;

    Abstract : In this thesis, we give a description of the detailed structure of the proton and a description of the final-state properties in electron-proton scattering. Qualitative results, in a purely gluonic scenario with the leading log approximation, and quantitative results, where quarks are included and some sub-leading corrections have been made, are presented.

    Abstract : 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. READ MORE

  6. 19. Extending the nuclear cranking model to tilted axis rotation and alternative mean field potentials

    Author : Peter Olivius; Matematisk fysik; []

    Abstract : The nuclear model for three dimensional cranking is extended to include a generalization of the Strutinski renormalization procedure from principal axis cranking to cranking about an tilted axis. A new computer code has been written for realistic, full-scale calculations within the three dimensional cranking model. READ MORE
