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

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

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

    Sammanfattning : 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. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Kärnfysik

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

    Sammanfattning : 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. LÄS MER

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

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

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

    Sammanfattning : 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. LÄS MER

  5. 4. 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

  7. 5. Studies of Light Hyperon Decay Parameters

    Kandidat-uppsats, Uppsala universitet/Kärnfysik

    Författare :Annele Heikkilä; [2019]
    Nyckelord :Hadron Physics; Hyperon; CP symmetry; Monte Carlo simulations; BESIII;

    Sammanfattning : A basic assumption in fundamental physics is that equal amounts of matter and antimatter were created after the Big Bang. When particles and antiparticles collide, they annihilate, i.e. disappear and produce photons. LÄS MER
