1. Analysis of Atmospheric Muon Bundles with IceCube
Master-uppsats, Uppsala universitet/HögenergifysikSammanfattning : This work is a preliminary study of the background of a search for dark, long-lived particles in the IceCube detector. The high flux of atmospheric muons in IceCube is considered background to the detector's primary science goal, which is to detect astrophysical neutrinos through the emission of Cherenkov radiation.

2. 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
3. Long-Lived Particles from exotic Higgs decays at the FCC-ee
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/HögenergifysikSammanfattning : This thesis presents the first sensitivity analysis for exotic Higgs boson decays at the electron-positron stage of the Future Circular Collider (FCC-ee) within the FCCAnalyses framework. The project studies the production of a Higgs boson in association with a Z boson in electron-positron collisions at a center-of-mass energy of 240 GeV, with the Higgs boson decaying into two long-lived scalars and the Z boson decaying leptonically.

4. Realistic Track and Event Reconstruction of the Ξ Hyperons at PANDA
Master-uppsats, Uppsala universitet/KärnfysikSammanfattning : The PANDA experiment at FAIR is an antiproton experiment and it will offer unique possibilities for the study of hadron physics including hyperon physics. With the PANDA detector, it will be possible to exclusively reconstruct hyperon-antihyperon events. LÄS MER
5. Constraining Physics Beyond the Standard Model with Emerging Jets using the ATLAS Experiment
Kandidat-uppsats, KTH/FysikSammanfattning : Dark matter, the unknown matter that constitutes 85% of all matter in the universe, is one of the greatest mysteries in fundamental physics. One theory that might explain dark matter predicts that there are long-lived particles known as dark pions. LÄS MER
