1. Physics at the High-Energy Frontier : Phenomenological Studies of Charged Higgs Bosons and Cosmic Neutrino Detection
Abstract : The Standard Model of particle physics successfully describes present collider data. Nevertheless, theoretical and cosmological results call for its extension. A softly broken supersymmetric completion around the TeV scale solves several of the outstanding issues. Supersymmetry requires two Higgs doublets, leading to five physical Higgs states. READ MORE

2. Searches for Particle Dark Matter : Dark stars, dark galaxies, dark halos and global supersymmetric fits
Abstract : The identity of dark matter is one of the key outstanding problems in both particle and astrophysics. In this thesis, I describe a number of complementary searches for particle dark matter. READ MORE

3. Nonlinear Evolution in High Energy QCD
Abstract : QCD at very high energies is still not very well understood. Difficulties arise from a strong non-linear dynamics and also from nonperturbative physics. Detailed analytic calculations are often only possible either for simple toy models, or for asymptotically high energies. READ MORE

4. Design of Thermal Energy Storage with Phase Change Materials - Investigations within Material, Device and System Scale
Abstract : The addition of a thermal energy storage (TES) into a process allows the operator to store and release thermal energy on demand. This increased process flexibility leads to potential benefits such as shifting energy demand from peak to off-peak hours. READ MORE

5. Aspects of Hadron Production in High-Energy Heavy-Ion Physics
Abstract : High-energy heavy-ion collisions provide a unique tool for the study of nuclear matter as a function of temperature and density. WA98 at the CERN SPS recorded data with a 158 A GeV Pb beam on a Pb target in 1996. To cope with the high charged-particle density, a tracking system based on high granularity multi-step avalanche detectors was developed. READ MORE
