1. Relativistic particle mechanics : a hamiltonian approach
Sammanfattning : This study is devoted to certain fundamental problems within theoretical physics. The aim is to show that there exists a consistent Poincare invariant Hamiltonian formalism describing interactions between any number of discrete particles forming an isolated (in general spinning) system. No fields or potentials are needed for the description. LÄS MER
2. On the construction of covariant models for spinning particles and their quantization
Sammanfattning : .... LÄS MER
3. Compact Relativistic Matter Shells with Massless and Charged Particles
Sammanfattning : The Vlasov model is a matter model that is widely used in physics. In the context of astrophysics and cosmology it describes an ensemble of self gravitating, collisionless particles. These particles can be interpreted as for example ions, stars, or galaxies. LÄS MER
4. Derivation and BRST Quantization of Models for Spinning Relativistic Particles
Sammanfattning : This thesis deals with the construction of models for spinning relativistic particles and their covariant quantization within a BRST framework. In the first part the ideas and methods which constitute the background to the papers are reviewed, and a summary of the main results obtained therein is given. The second part consists of the papers. 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
