2. 1. Mini-Jet Production in Proton-Antiproton Interactions and Particle Production in Heavy-Ion Collisions

   Author : Haiqiao Wang; Partikel- och kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; proton antiproton interaction; Quark-gluon plasma; dynamical fluctuation; intermittency; limiting fragmentation; intranuclear cascading; target fragmentation; heavy-ion collision; image processing; mini-jet; Nuclear physics; Kärnfysik; Fysicumarkivet A:1997:Wang;

   Abstract : The thesis is based on the data analysis and detector development of the EMU01/CERN, E863/BNL and UA1/CERN experiments. Particle fluctuations are studied with the scaled factorial moments in the fragmentation region of oxygen-induced emulsion interactions from 3.7 to 200 A GeV. READ MORE

4. 2. ALPACA - A kinetic theory Monte Carlo event generator for heavy ion collisions

   Author : Robin Törnkvist; Partikel- och kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ALPACA; QCD effective kinetic theory; event generators; heavy-ion physics; Proton-proton collisions; small system collectivity; phenomemology;

   Abstract : Recent measurements of collective effect-like signals in small collision systems has highlighted the need for new models to explain these phenomena. One good candidate for such a model is the AMY QCD effective kinetic theory, which is valid for systems in- and out-of-equilibrium. READ MORE

5. 3. Development of Detector Systems for Internal and Fixed Target Heavy Ion Physics Experiments

   Author : Pavel Golubev; Kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multi-detector system; VLSI electronics; ultra-thin detectors; heavy ion reactions; nuclear intensity interferometry; Kärnfysik; Nuclear physics; ultra-high vacuum compatibility; Fysicumarkivet A:2003:Golubev;

   Abstract : This thesis deals with intermediate energy heavy ion reactions with the particular aim to study the nuclear matter equation of state which defines the relation between statistical parameters of a fermionic system. The development of equipment for two experiments, CA47 at The Svedberg Laboratory in Uppsala, Sweden and R16 at Kernfysisch Versneller Instituut (KVI), Groningen, The Netherlands, are described.

6. 4. Developing the Angantyr model and extending colour reconnection for heavy-ion collisions in Pythia

   Author : Harsh Shah; Partikel- och kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; heavy-ion collisions; hadronization; QCD Phenomenology; Colour Reconnection; Fysicumarkivet A:2023:Shah;

   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

7. 5. On Experimental and Theoretical Studies of Dynamics and Particle Production in p+Nucleus and Heavy Ion Reactions

   Author : Anton B Fokin; Partikel- och kärnfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; heavy-ion collisions; excitation function; subthreshold pion production; collective effects; entropy and chaos production; d p ratio; molecular dynamics; artificial neural networks; multifragmentation; Physics; Fysik; Fysicumarkivet A:1998:Fokin;

   Abstract : Several experiments and theoretical models of intermediate energy heavy ion collision physics are presented in this thesis. Statistical and dynamical aspects of nuclear collisions are widely discussed these days, particularly in connection with the multifragmentation phenomenon and the possible link to a liquid-gas phase transition in the spinodal region of nuclear matter phase diagram.
