  1. 1. The last unknown leading order low-energy constant of chiral perturbation theory

    Master-uppsats, Uppsala universitet/Kärnfysik

    Författare :Magnus Bertilsson; [2024]
    Nyckelord :QCD; Form factors; Vector form factors; Chiral perturbation theory; Hadrons; Hadron physics; hyperon decay; semileptonic decay;

    Sammanfattning : .... LÄS MER

  3. 2. Three-body decay as a baryon polarizer

    Kandidat-uppsats, Uppsala universitet/Kärnfysik

    Författare :Carl Johan Königsson; [2023]
    Nyckelord :Three-body decay; polarization; CP violation; hyperon; resonance; Trekroppssönderfall; polarisation; CP-brytning; hyperon; resonans;

    Sammanfattning : 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. LÄS MER

  4. 3. Studies of the J/Ψ → anti-Σ0Σ0 Reaction with BESIII : Event Selection Development

    Master-uppsats, Uppsala universitet/Kärnfysik

    Författare :Benjamin Verbeek; [2023]
    Nyckelord :hyperon; CP; symmetry; event selection; tracks; BES; BESIII; USTC;

    Sammanfattning : The apparent symmetry between matter and antimatter raises the question of why the universe consists of mostly matter. Via an academic exchange to USTC Hefei, a reaction was studied that aims to give insight into this question. LÄS MER

  5. 4. On the vector transition form factors in the Ω- → Ξ0 W- decay

    Master-uppsats, Uppsala universitet/Kärnfysik

    Författare :Magnus Bertilsson; [2023]
    Nyckelord :QCD; Form factors; Vector form factors; Chiral perturbation theory; One-loop diagrams; Hadrons; Hadron physics; Hyperon decay; Hadron structure;

    Sammanfattning : To learn more about the structure of hadrons we study form factors. In the semi-leptonic decay Ω- → Ξ0W- two types of form factors arise namely the vector and axial-vector transition form factors. LÄS MER

  7. 5. 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
