  1. 1. Analysis of Simulated Charm Baryons : Decay Kinematics and Parameter Estimations for Studies with the Belle II Experiment

    Kandidat-uppsats,

    Författare :Elsa Spengler; Sara Bjursten; [2023]
    Nyckelord :CP-symmetry; charm baryon; estimation; generator; Belle II;

    Sammanfattning : A fundamental assumption of our universe has been that equal amounts of matter and antimatter were created during the Big Bang. Since the world we live in is made entirely of matter, one either needs to question this assumption, or explain how matter was enriched with respect to antimatter. LÄS MER

  3. 2. Maximum Likelihood Estimation of Hyperon Parameters in Python : Facilitating Novel Studies of Fundamental Symmetries with Modern Software Tools

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Benjamin Verbeek; [2021]
    Nyckelord :CP-symmetry; maximum log-likelihood; python; estimation; BESIII; PANDA; hyperon; numba;

    Sammanfattning : In this project, an algorithm has been implemented in Python to estimate the parameters describing the production and decay of a spin 1/2 baryon - antibaryon pair. This decay can give clues about a fundamental asymmetry between matter and antimatter. LÄS MER

  4. 3. 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

  5. 4. Near detector simulation studies for CP violation discovery with ESSnuSB

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :In-Pyo Yeo; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The neutrino oscillation experiment ESSnuSB aims to measure the CP violation phase in the lepton sector with an intense neutrino beam produced at ESS. If the CP violation is discovered, then the matter-antimatter asymmetry of the Universe can be possibly explained. LÄS MER

  7. 5. CP-violation in Supernova Neutrino Oscillations

    Master-uppsats, Linköpings universitet/Teoretisk Fysik; Linköpings universitet/Tekniska högskolan

    Författare :Jessica Elevant; [2014]
    Nyckelord :CP-violation; δ-phase; neutrino oscillation; three-flavour; supernova;

    Sammanfattning : It is astonishing both how little and how much we know about neutrinos. On one hand, the neutrino is the second most abundant particle in our Universe. Neutrinos may be created in the Sun, core collapse supernovae, cosmic rays, geological background radiation, supernova remnants and in the Big Bang. LÄS MER
