  2. 1. The Charm of Excited Glue : Charmonium in e+e– and ppbar collisions

    Author : Agnes Lundborg; Ulrich Wiedner; Helmuth Koch; Uppsala universitet; []
    Keywords : Physics; hadron; charmonium; PANDA; antiproton; annihilations; spin-parity exotics; gluonic excitations; BES; hybrid; glueball; resonances; radiative decays; electromagnetic transitions; Fysik;

    Abstract : This thesis treats the mass range of charmonium states and excited gluonic fields in two experiments, BESII and PANDA, and outlines a phenomenological model that connects them.In BESII, e+e– form a charmonium initial state, which is utilised as a source for secondary particles.

  4. 2. On a Hydrogen Pellet Target for Antiproton Physics with PANDA

    Author : Örjan Nordhage; Ulrich Wiedner; Eberhard Widmann; Uppsala universitet; []
    Keywords : Nuclear physics; PANDA; Internal target; Pellet target; Beam-target interaction; Vacuum; Tracking; D-meson decay length; Kärnfysik;

    Abstract : The PANDA experiment is a part of the future FAIR accelerator facility and will study the strong interaction by detecting the reaction products from antiproton-proton annihilations in a near full solid-angle configuration. One option for the internal proton target in PANDA is frozen micro-spheres of hydrogen, so-called pellets. READ MORE
