1. Gravitational Collapse of a Massless Scalar Field in a Theory of Minimally Modified Gravity
University essay from KTH/FysikAbstract : This thesis explores the spherically symmetric gravitational collapse of a massless scalar field in a minimally modified gravity theory denoted VCDM (V replaces $\Lambda$ in the $\Lambda$CDM abbreviation), a class of theories propagating the same degrees of freedom as general relativity at the expense of broken 4D diffeomorphism invariance. Numerical evolution of the equations of motion reveals that for small initial scalar profile amplitudes, no black hole forms from the collapse. READ MORE

2. Exploring Diffuse Supernova Neutrino Background in Hyper-Kamiokande
University essay from KTH/FysikAbstract : This thesis studies the Diffuse Supernova Neutrino Background (DSNB) that is expected to be detected in the future neutrino detector Hyper-Hamiokande. DSNB refers to the flux which is made up of neutrinos from all past core-collapsing supernova explosions. READ MORE

3. Determining backgrounds with misidentified leptons in the ATLAS Higgs boson analysis
University essay from KTH/FysikAbstract : This thesis presents an analysis of misidentified leptons in the Higgs boson decaychannel H → W W ∗ → lνlν. Misidentified leptons, resulting from jets misidentifiedas leptons, mimic the signal of a Higgs boson decay, resulting in a backgroundcontribution to the signal. READ MORE

4. Three-body decay as a baryon polarizer
University essay from Uppsala universitet/KärnfysikAbstract : According to the standard model, the size of CP violation in the weak decay Λ → pπ- is predicted to be ∼ 10-5. This means that a very high precision is needed if we want to be able to measure it. READ MORE

5. Isocyanates formation from thermal degradation of polyurethane foam during welding of district heating pipes
University essay from KTH/ErgonomiAbstract : Polyurethane insulation foam, which is used as insulation on district heating steel and copper pipes, is made from polymerisation of polyol and diisocyanates monomers. Installation of new district heating pipes or replacement of old pipes involves masses of welding activities. READ MORE
