1. Hadronization Effects in the Strong Interaction
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

2. Properties of Hadronization in e+e- -Annihilation
Abstract : Possible effects from colour interferences in strong interactions are discussed and investigated, and possible experimental signals in e+e- --> hadrons and e+e- --> W+W- --> hadrons are suggested. The observability of the signals depend on the relative probabilities of the occurrence of interferences, and can provide a measurement of the probabilities. READ MORE

3. Rope Hadronization, Geometry and Particle Production in pp and pA Collisions
Abstract : This thesis concerns models of high energy collisions of sub-atomic particles, and the models’ implementation in numerical simulations; so–called Monte Carlo event generators. The models put forth in the thesis improves the description of soft collisions of protons, and takes the first steps towards a new, microscopic description of collectivity in proton collisions and collisions of heavy nuclei such as lead.

4. Luminosity evaluation and fragmentation studies for the DELPHI experiment at LEP
Abstract : The first subject addressed in this thesis is the contribution of the VSAT luminosity to the lineshape analysis, i.e. to the extraction of the mass and width of the Z0 boson from LEP1 DELPHI data. The VSAT detector has contributed to the lineshape parameter determination by providing a relative luminosity measurement of high accuracy. READ MORE

5. Developing the Angantyr model and extending colour reconnection for heavy-ion collisions in Pythia
Abstract : This thesis is composed of four papers, the first two show the attempts made to extend the Pythia event generator to simulate heavy-ion collision events. The other two papers show methods to improve the hadronization mechanism in the Pythia model for a bettter agreement with the experimental data of pp and heavy-ion collisions. READ MORE
