1. The Higgs Width in Higgs production in association with a W+ boson
Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisationSammanfattning : The width of the Higgs boson is a quantity that cannot be measured directly from the on-shell Higgs peak; it would have to be measured indirectly. In 2013, Caola and Melnikov developed a method to determine the Higgs width by using off-shell and on-shell cross-sections and applying the narrow-width approximation. LÄS MER
2. Trigger-Level Multiple Electron Event Classification with LDMX using Artificial Neural Networks
Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : Artificial neural networks is a powerful tool for classifying and identifying patterns in large amounts of data. One of the possible tasks of these networks is classification of data into categories. LÄS MER
3. Void Evolution and Cosmic Star Formation
Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : The rate at which stars have formed throughout the history of theuniverse is not constant, it started out slow, increased until around redshift ∼ 2 when it reversed and became slower again. The reason for this behaviour is still being investigated with various models and simulations usually based upon dark matter halos. LÄS MER
4. Can Dwarf Galaxies Tell Us How the Milky Way Formed?
Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : Dwarf galaxies are a key component in understanding the evolution of galaxies and provide tests on the standard cosmological $\Lambda$ Cold Dark Matter model. According to the formation hierarchy, dwarf galaxies are the pieces that create all galaxies. Our current understanding of dwarf galaxies faces discrepancies between theory and observations. LÄS MER
5. Beyond Dark Tourism
Magister-uppsats, Södertörns högskola/TurismvetenskapSammanfattning : Background: The development of Dark Tourism has evolved much over recent years. The term Dark Tourism is too general for a subject matter that is multilayered and complex. Aim of the Thesis and Research Question: Is to present the consistencies, vagueness, and disagreements of the different categorizations in Dark Tourism. LÄS MER
