  1. 1. Probing Charm Production with Three-Particle Correlations in pp Collisions

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

    Author : Kim Haupt; [2023]
    Keywords : pp collisions; charm production; three-particle correlation; Pythia; Physics and Astronomy;

    Abstract : This thesis aims to investigate possible correlations between charm production and baryon production in proton-proton collisions through three-particle correlations. The question attempted to be answered is where, for a given charmed baryon, the balancing anti-charm particle and balancing anti-baryon are located. READ MORE

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

    University essay from Uppsala universitet/Kärnfysik

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

    Abstract : 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. READ MORE

  4. 3. The Strong Potential of ΛΛ Femtoscopy at HADES

    University essay from Uppsala universitet/Kärnfysik

    Author : Malin Bohman; [2022]
    Keywords : hyperon; hyperons; Λ hyperon; ΛΛ; femtoscopy; correlation studies; strong interaction; hyperon interaction; hyperon interactions; HADES;

    Abstract : The aims of this thesis project have been to determine the feasibility of hyperon reconstruction utilizing a newly developed and implemented vertex fitter based on the Lagrange multiplier method. This was achieved through simulation and subsequent analysis of the reaction specified below, detailing the production of Λ-hyperon and K+ -meson pairs from proton-proton collisions. READ MORE

  5. 4. Radiative Corrections Beyond the Soft-Photon Approximation

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Jacob Lindahl; [2021]
    Keywords : Soft-Photon Approximation; Bremsstrahlung Correction; Transition Form Factor; Radiative Corrections; Physics and Astronomy;

    Abstract : This thesis calculates the bremsstrahlung correction beyond the soft-photon approximation for the decay ω → π0 l+ l- . The effect of the radiative corrections on the extraction of the transition form factor from data is investigated. READ MORE
