  1. 1. 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

  3. 2. Study of the decay modes of Ξc0→pK−K−π+ with the LHCb experiment.

    Kandidat-uppsats, Uppsala universitet/Kärnfysik

    Författare :Yuliya Bilinskaya; [2022]
    Nyckelord :Particle physics; hadron physics; resonance; particle decay; LHCb; Dalitz plot; Lambda resonance; Delta resonance;

    Sammanfattning : This thesis reports the first indications of the Λ(1520) and ∆(1232)++ decay modes in the Ξc0 → pK−K−π+ decay. The obtained fractions relative the inclusive Ξc0 → pK−K−π+ decay are (6.4±0.6)% and (32. LÄS MER

  4. 3. Dalitz Plot Analysis of η'→ηπ+π-

    Master-uppsats, Uppsala universitet/Kärnfysik

    Författare :Simon Taylor; [2020]
    Nyckelord :Dalitz Plot Analysis; BESIII; meson physics; maximum likelihood method; chi2 method;

    Sammanfattning : Chiral Perturbation Theory (ChPT) is a tool for studying the strong interaction at low energies. The Perturbation theory is developed around the limit where the light quarks, u,d,s are approximated to be massless. In this approximation the isospin symmetry, one of the main features of the strong interaction, is fulfilled automatically. LÄS MER
