1. 1. Meson production in pd collisions

   Författare :Karin Schönning; Jozef Zlomanczuk; Bo Höistad; Susan Schadmand; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; meson production; measured angular distribution; total cross section; polarisation; Nuclear physics; Kärnfysik; Nuclear Physics; kärnfysik;

   Sammanfattning : Meson production in proton-deuteron collisions has been studied using the WASA detector facility at the CELSIUS storage ring in Uppsala. Data were obtained at two different beam energies, 1360 MeV and 1450 MeV, slightly above threshold for η and ω mesons. LÄS MER

3. 2. Towards a realistic hyperon reconstruction with PANDA at FAIR

   Författare :Adeel Akram; Karin Schönning; Michael Papenbrock; Carl Nettelblad; Marek Jacewicz; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hyperon; Extended Target; Tracking; PANDA; FAIR; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

   Sammanfattning : The goal of the PANDA (anti-Proton ANnihilation at DArmstadt) experiment at FAIR (Facility for Anti-proton and Ion Research) is to study strong interactions in the confinement domain. In PANDA, a continuous beam of anti-protons () will impinge on a fixed hydrogen (p) target inside the High Energy Storage Ring (HESR), a feature intended to attain high interaction rates for various physics studies e.

5. 4. 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

7. 5. Improving the Neutron Cross-section Standards 238U(n,f) and 6Li(n,a) : Measurements and Simulations

   Författare :Kaj Jansson; Cecilia Gustavsson; Karin Schönning; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

   Sammanfattning : Improving or extending the range of cross-section standards, which in general are believed to be well known, require good control of the experimental conditions and the uncertainties involved. Two experiments that aspire to improve two different neutron cross-section standards, 238U(n,f) and 6Li(n,a, are presented in this thesis. LÄS MER
