   Sammanfattning : The present thesis describes two experiments performed in the storage ring CELSIUS at The Svedberg Laboratory in Uppsala. In the first experiment the importance of three - nucleon clustering in the six - nucelon system was investigated. The total cross section for the production of the ground state and the 3. LÄS MER

4. 3. Studies of the Decay η→π+π-π0 with WASA-at-COSY

   Författare :Patrik Adlarson; Jozef Zlomanczuk; Bo Höistad; Fabio Bossi; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Chiral Perturbation Theory; Isospin violation; Quark masses; Symmetries; Advanced Instrumentation; Nuclear Physics; Kärnfysik;

   Sammanfattning : In 2008 a large statistics sample of approximately 1·107 η-decays has been collected with the WASA detector at COSY using the pd→3Heη reaction at the beam kinetic energy of 1 GeV. These data are being used to study the not so rare η decays involving charged pions, like η→π+π-π0. LÄS MER

5. 4. Measurement of the Reaction pp→ppπ+π-π0 with CELSIUS/WASA at 1.36 GeV

   Författare :Marek Jacewicz; Sven Kullander; Hans Ströher; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elementary particle physics; Elementarpartikelfysik; Elementary particle physics; Elementarpartikelfysik;

   Sammanfattning : A versatile detector setup prepared by the CELSIUS/WASA collaboration for exclusive studies of rare processes produced in proton and deuteron collisions with hydrogen and deuterium pellet targets is presented. For the near-threshold production of light mesons, π0 and η, the scattered beam and target particles are measured in the forward detector, while the products of the decaying mesons are registered in a central detector covering close-to-4π sr.
