1. 1. Analysis of Atmospheric Muon Bundles with IceCube

   Master-uppsats, Uppsala universitet/Högenergifysik

   Författare :Anna Selina Neyer; [2024]
   Nyckelord :;

   Sammanfattning : 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.

3. 2. Long-Lived Particles from exotic Higgs decays at the FCC-ee

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

   Författare :Magdalena Vande Voorde; [2023]
   Nyckelord :;

   Sammanfattning : 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. 3. Realistic Track and Event Reconstruction of the Ξ Hyperons at PANDA

   Master-uppsats, Uppsala universitet/Kärnfysik

   Författare :Vitor Jose Shen; [2023]
   Nyckelord :Hyperon; Cascade Particle; PANDA Experiment; Tracking Algorithm; Track Evaluation; Track Reconstruction; Event Reconstruction;

   Sammanfattning : 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. 4. Constraining Physics Beyond the Standard Model with Emerging Jets using the ATLAS Experiment

   Kandidat-uppsats, KTH/Fysik

   Författare :Simon Thor; [2022]
   Nyckelord :ATLAS; CERN; particle physics; simulation; Python; C ; standard model; emerging jets; long-lived particles;

   Sammanfattning : 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

7. 5. Long-Lived Heavy Neutral Leptons at the FCC-ee

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

   Författare :Lovisa Rygaard; [2022]
   Nyckelord :;

   Sammanfattning : The Future Circular electron-positron Collider (FCC-ee) is a high luminosity frontier particle accelerator for high precision measurements of the heaviest fundamental particles and possible evidence of new physics. Heavy Neutral Leptons (HNLs) are examples of new particles with discovery potential at the FCC-ee that could answer some of the most substantial questions in particle physics, such as how neutrinos oscillate between flavour eigenstates.
