1. Correlations in multiparticle production
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
2. QCD Phenomenology of Heavy Particle Dynamics
Sammanfattning : In this thesis the phenomenology of Quantum Chromo Dynamics (QCD) is studied in a variety of circumstances from both perturbative and non-perturbative perspectives. The main emphasis is on the production and hadronization of heavy particles, specifically heavy quarks, gauge bosons, leptoquarks and supersymmetric particles. LÄS MER
3. Multiparticle Production in Strong Interactions
Sammanfattning : An alternative formulation of the Lund fragmentation model for string states without gluons is presented. It is shown that the fragmentation process can be factorised into a product of transition operators with well-defined eigenfunctions and corresponding eigenvalues. LÄS MER
4. Hadronization Effects in the Strong Interaction
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
5. Colour Reconnection and Weak Showers
Sammanfattning : This thesis consider the improvement of the simulation tools used to describe high energy particle collisions. These simulation programs are normally referred to as event generators. LÄS MER
