    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Quark masses; Hadronic decays; Light mesons; Meson-meson interactions; Fysik med inriktning mot kärnfysik; Physics with specialization in Nuclear Physics;

    Sammanfattning : The mechanism of the isospin violating η→π+π−π0 decay is studied in a high precision experiment using a Dalitz plot analysis. The process is sensitive to the difference between up and down quark masses. LÄS MER

  4. 3. PWO Crystal Measurements and Simulation Studies of Anti-Hyperon Polarisation for PANDA

    Sammanfattning : The Gesellschaft für Schwerionenforschung (GSI) facility in Darmstadt, Germany, will be upgraded to accommodate a new generation of physics experiments. The future accelerator facility will be called FAIR and one of the experimentsat the site will be PANDA, which aims at performing hadron physics investigations by colliding anti-protons with protons.

  5. 4. Studies of PWO Crystals and Simulations of the p̅p →Λ̅Λ, Λ̅Σ0 Reactions for the PANDA Experiment

    Författare :Sophie Grape; Tord Johansson; Per-Erik Tegnér; Kai-Thomas Brinkmann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PANDA; antiproton; PWO; hyperon; lambda; simulation; polarisation; spin correlation; Nuclear physics; Kärnfysik; Physics; fysik;

    Sammanfattning : The thesis comprises investigations of two topics related to the PANDA experiment. The first part is dedicated to energy resolution and light yield uniformity studies of PWO crystals for the electromagnetic calorimeter. The second part of the thesis is dedicated to simulation studies of the p̅p→Λ̅Λ and the p̅p→Λ̅Σ0 channels. LÄS MER

  7. 5. Hadronic Decays of the ω Meson

    Författare :Lena Heijkenskjöld; Andrzej Kupsc; Tord Johansson; Michael Ostrick; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Hadronic decays; Light mesons; Meson-meson interactions; Fysik med inriktning mot kärnfysik; Physics with specialization in Nuclear Physics;

    Sammanfattning : Two decay channels of the ω(782) meson, into π+π-π0 and π+π-, are studied. The dynamics of the three-pion channel is represented using a two-dimensional distribution, called a Dalitz plot. A high-statistics Dalitz plot distribution is needed to test theoretical predictions and increase understanding of the decay mechanism. LÄS MER
