1. 31. Studies of Dark Showers for Present and Future Colliders

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Nicoline Krogh Hemme; [2022]
   Keywords : high-energy particle physics; dark matter; collider physics; beyond the standard model; Physics and Astronomy;

   Abstract : In this work we explore a strongly-interacting dark sector with a Z’ portal to the Standard Model. We focus on the dark shower phenomenology and their semi-visible jet signatures with a strong emphasis on first principles of the theory. READ MORE

3. 32. Dwarf Galaxies in the Galactic Potential as probes of its internal structure

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Arn Marklund; [2022]
   Keywords : Numerical integration; Stellar Streams; Dwarf Galaxies; Dark Matter; Physics and Astronomy;

   Abstract : Satellite galaxies on bound orbits around the Milky Way (MW) are constantly subject to tidal forces from the MW. If the tidal forces are large enough, they may strip the outermost stars of the satellite, that in turn distribute themselves in long elongated stellar streams. READ MORE

4. 33. Background Studies of the High-Intensity Baryon Extraction and Measurement (HIBEAM) Experiment at the European Spallation Source

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Blahoslav Rataj; [2021]
   Keywords : Physics and Astronomy;

   Abstract : The High-Intensity Baryon Extraction and Measurement experiment (HIBEAM) is proposed as one of the experimental stations at the European Spallation Source (ESS). This experiment will mainly focus on the neutron into sterile neutron oscillations which violate the baryon number (B) by one unit. READ MORE

5. 34. General Relativity and Dynamical Universes

   University essay from Uppsala universitet/Teoretisk fysik

   Author : Kajsa Fransson; [2021]
   Keywords : cosmology; general relativity; scale factor; friedmann equation;

   Abstract : The aim of this report is to explore different models of cosmology, depending on components as matter, radiation and dark energy. To be able to investigate the behaviour and age of these model universes, it is necessary to solve the Friedmann equation. READ MORE

6. 35. Primordial Gravitational Waves and ultra-light Dark Matter in a complex singlet extended Standard Model

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Sara Wildenor; [2021]
   Keywords : theoretical physics; gravitational waves; dark matter; complex singlet extended standard model; LISA; BBO; DECIGO; Physics and Astronomy;

   Abstract : In this thesis, the consequences of extending the internal symmetries of the standard model with a complex singlet scalar field, are investigated in terms of dark matter phenomenology and the possibility of primordial gravitational wave detection utilizing space based laser interferometry. The scalar potential of the model is constructed with a Z2 symmetry, which allows for the retainment of a linear and a quadratic coupling parameter, as well as a stable dark matter candidate, and an additional non-zero vacuum expectation value for the real component of the scalar field.
