1. Multiparton Interaction Models and Parton Shower Studies
Sammanfattning : This thesis involves phenomenological models for describing high energy particle collisions. One class of these models, multiparton interactions (MPI), deals with the fact that when colliding two hadrons, it is possible for more than one pair of their constituents to interact. LÄS MER
2. Production of strangeness in partonic interactions at the LHC
Sammanfattning : The strong interaction is responsible for nearly all observable baryonic matter in the Universe. Quantum Chromodynamics, which describes interactions between quarks and gluons, however, cannot be solved analytically in the non-perturbative regime, involving low momentum transfers. LÄS MER
3. 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
4. Quantum chromodynamics and colour singlet exchange in high energy interactions
Sammanfattning : Quantum chromodynamics (QCD) is the fundamental theory in elementary particle physics that describes the strong interaction in terms of exchanges of force-carrying, colour-charged particles known as gluons. Although well-established through experimental verifications, there are fundamental unsolved problems in the theory. LÄS MER
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
