Publication abstract: 

The PANDA experiment at FAIR in Darmstadt (Germany), which is currently under construction, will provide excellent opportunities to search for exotic states in anitproton-proton annihilations. Various experiments observed tensor resonances in the phiphi system in the same mass region where Lattice QCD calculations predict the tensor glueball. The determined magnitude of the reaction exceeds expectations from a simple application of the OZI rule by two orders of magnitude, which was interpreted as a hint for a possible intermediate glueball state. Therefore, the reaction pbarp->phiphi is considered to offer a gluonrich environment and will be studied at PANDA by performing an energy scan at center of mass energies between about 2.25 GeV and 2.6 GeV. Contributing resonances in the phiphi system can then be identified by means of a mass independent partial wave analysis. In this contribution, studies will be presented that have been carried out in order to address the feasibility to identify contributing resonances produced in this formation process, utilizing the partial wave analysis software PAWIAN.
