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

2. From Strange to Charm : Meson production in electron-positron collisions
Sammanfattning : 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. LÄS MER
3. Modeling of Electron Cooling : Theory, Data and Applications
Sammanfattning : 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. LÄS MER
