1. The colour of gluon interactions : Studies of Quantum Chromodynamics in soft and hard processes
Sammanfattning : Quantum Chromodynamics (QCD) is the theory of the strong interaction, one of the fundamental forces of nature. The interactions between quarks are mediated by gluons, which are the colour-charged gauge fields in QCD. LÄS MER
2. Studies of the fragmentation process in hadronic decays of Z⁰ boson
Sammanfattning : This thesis is based on the work that was done during 1992--1996 at the DELPHI detector at LEP. Its main parts are outlined below. The brief Introduction gives an overview of the science of Particle Physics, its development and contemporary status. LÄS MER
3. Investigation of Quark Gluon Plasma-like signals with Lund string interactions
Sammanfattning : This thesis investigates the interactions that occur in extreme densities for high-energy collisions of subatomic particles. The theoretical models developed for this purpose are based on the Lund model. The developments have been implemented as a new module called Gleipnir to the Monte-Carlo event generator, P YTHIA .

4. Λ/K0s Associated with a Jet in Central Pb–Pb Collisions at √sNN = 2.76 TeV Measured with the ALICE Detector
Sammanfattning : In high energy heavy ion collisions, the QCD matter undergoes a phase transition to a hot and dense strongly coupled Quark Gluon Plasma, where quarks and gluons are deconfined in a volume of nuclear dimensions. At intermediate pT, 2 < p T < 8 GeV/c, a decoupling from pure hydrodynamical flow is observed, most noticeable in central collisions, demonstrated by the peak in the ratio of baryons to mesons, e.

5. Net-Charge Fluctuations in Ultra-Relativistic Nucleus-Nucleus Collisions
Sammanfattning : PHENIX is one of four experiments at the Relativistic Heavy-Ion Collider, RHIC. The high-energy heavy-ion collisions provided by this accelerator offer the possibility to study nuclear matter at high temperature and density. The high multiplicity of particles produced in these collisions puts high demands on detector performance. LÄS MER
