1. 1. Exploring the Merits and Challenges of Hyperon Physics : with PANDA at FAIR

   Författare :Walter Ikegami Andersson; Karin Schönning; Michael Papenbrock; Tord Johansson; Volker Crede; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Hyperon; Track reconstruction; Non-perturbative QCD; Spin observables; PANDA; Fysik med inriktning mot kärnfysik; Physics with specialization in Nuclear Physics;

   Sammanfattning : Binary hyperon production in antiproton-proton annihilations will be carried out with the PANDA experiment at FAIR, and probes the strong interaction in the non-perturbative regime where the relevant degrees of freedom are unclear. The self-analyzing decays of hyperons provide a straightforward way to study reaction dynamics via the measurement of spin observables. LÄS MER

3. 2. Multi-Strange and Charmed Antihyperon-Hyperon Physics for PANDA

   Författare :Erik Thomé; Tord Johansson; Brian Quinn; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PANDA; FAIR; antiproton; hyperon; strangeness; charm; polarisation; spin correlation; CP violation; Nuclear Physics; Kärnfysik;

   Sammanfattning : The prospects of studying multi-strange and charmed antihyperon-hyperon physics and CP violation in hyperon decays in the upcoming PANDA experiment at FAIR, Germany, have been studied in this thesis.The angular dependence on polarisation parameters in the decay of the spin 3/2 Omega hyperon was calculated using the density matrix formalism.

4. 3. 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

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

   Författare :Sophie Grape; Tord Johansson; Thomas Nilsson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PANDA; PWO; antiproton; hyperon; polarisation; Nuclear physics; Kärnfysik; Kärnfysik; Nuclear Physics;

   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.

7. 5. Hadron Physics in a Polarized World : Exploring Electromagnetic Interactions with Spin Observables

   Författare :Viktor Thorén; Andrzej Kupsc; Karin Schönning; Magnus Wolke; David Ireland; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadron; Hyperon; Meson; Polarization; Spin observables; Electromagnetic interactions; BESIII; Fysik med inriktning mot kärnfysik; Physics with specialization in Nuclear Physics;

   Sammanfattning : The electromagnetic interactions of hadrons serve as a valuable probe of the nature of the strong force at low energies and simultaneously allow for tests of fundamental discrete symmetries. In this thesis, I show how polarization observables can be used to gain an in-depth understanding of these processes and present two analyses of data from the BESIII experiment where such observables have been studied.
