  1. 11. Complementarity of high energy and high intensity experiments for dark photon benchmarks

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

    Author : Joshua Greaves; [2022]
    Keywords : Dark matter; LDMX; Dark photon; Complementarity; Snowmass; Relic density; Thermal relic; Relic abundance; Cross section; Constraints; Limits; Minimal models; Energy frontier; Intensity frontier; Madgraph; Madanalysis; Vector mediated; Physics and Astronomy;

    Abstract : Physical phenomena that are unexplained by the Standard Model (SM) of particle physics, are the subject of the area of research known as physics Beyond the Standard Model (BSM). BSM physics contains many Dark Matter (DM) theories which have emerged; from particles such as axions, neutrinos, and Weakly Interacting Massive Particles (WIMPs), to primordial black holes and others.

  3. 12. Rare Weak Decays of the Omega Baryon

    University essay from Uppsala universitet/Kärnfysik

    Author : Cornelis Johannes Gerardus Mommers; [2022]
    Keywords : hadron; physics; nuclear; particle;

    Abstract : We study rare decays of the Omega baryon using SU(3) chiral perturbation theory, a successfuleffective field theory of quantum chromodynamics at low energies. At leading-order, we calculatethe branching fractions of the decay Ω− → Ξππ for all possible combinations of pions. READ MORE

  4. 13. CP Violation Studies in Cascade Decay Sequence

    University essay from Uppsala universitet/Kärnfysik

    Author : Roman Sultanov; [2022]
    Keywords : CP violation; cascade; decay; asymmetry parameters; polarisation; uncertainty;

    Abstract : This thesis studies CP violation in the decay of the Ξ− hyperon, also known as the cascade baryon, which decays in the sequence Ξ− → Λπ− → pπ−π−. A difference between the angular distribution of this decay sequence and the angular distribution of the charge conjugate decay sequence ͞Ξ+ →͞Λπ+ → ͞pπ+π+, after taking into account the inversion of the momenta due to the parity operation, is indicative of CP violation.

  5. 14. Dead layer determination for the new implantation detector of the LUNDIUM decay station

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Eleftheria Kosta; [2022]
    Keywords : Physics and Astronomy;

    Abstract : The Nuclear Structure Group in Lund, focuses on nuclear spectroscopy of decays of rare isotopes. A new decay station, called LUNDIUM, is currently being built, which will involve silicon and germanium detectors for the study of these nuclei. This thesis focuses on the characterization of one of the new silicon detectors, the implantation one. READ MORE

  6. 15. Assessment of the Capability for Vetoing Beta-Decay Events in the Lundium Decay Station

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Tanvir Sayed; [2022]
    Keywords : Radioactivity; Decays; Radiation; Ionisation; Superheavies; Exotic isotopes; Decay spectroscopy; Semiconductors; Silicon-Strip Detectors; Lundium; Vetoing; Electron spread; Particle identification; Physics and Astronomy;

    Abstract : Alpha decay spectroscopy using the latest and most sensitive detector setup as well as fast sampling read-out electronics has become very important for discovery and analysis of short-lived nuclei created in collision experiments in the laboratory. The Nuclear Structure Group in Lund is currently developing the Lundium Decay Station for use in comprehensive nuclear spectroscopy of decays for rare isotopes, particularly in the heavy & superheavy region.
