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. From Strange to Charm : Meson production in electron-positron collisions

   Author : Joachim Pettersson; Karin Schönning; Andrzej Kupsc; Simon Eidelman; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Hadronic decays; Light mesons; Charmonium; Meson production; BESIII; Fysik med inriktning mot kärnfysik; Physics with specialization in Nuclear Physics;

   Abstract : Decays of pseudoscalar mesons into a lepton-antilepton pair are very rare within the Standard Model since they cannot proceed via a single photon process. The C-even neutral mesons can be produced in electron-positron collisions by a two-photon intermediate state. READ MORE

5. 3. Modeling of Electron Cooling : Theory, Data and Applications

   Author : Karin Rathsman; Tord Johansson; Pia Thörngren; Dieter Prasuhn; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electron cooling; Beam dynamics; Vlasov technique; Nonlinear damping; Monte Carlo simulations; Nuclear physics; Kärnfysik; Nuclear Physics; Kärnfysik;

   Abstract : The Vlasov technique is used to model the electron cooling force. Limitations of the applicability of the method is obtained by considering the perturbations of the electron plasma. READ MORE
