The study of baryon excitation spectra provides insight into the inner structure of baryons. So far, most of the world-wide efforts have been directed towards N∗ and Δ spectroscopy. Nevertheless, the study of the double and triple strange baryon spectrum provides independent information to the N∗ and Δ spectra. The future antiproton experiment PANDA will provide direct access to final states containing a ΞˉΞ pair, for which production cross sections up to μb are expected in pˉp reactions. With a luminosity of L=1031cm−2s−1 in the first phase of the experiment, the expected cross sections correspond to a production rate of ∼106 events/day. With a nearly 4π detector acceptance, PANDA will thus be a hyperon factory. In this study, reactions of the type pˉp→Ξˉ+Ξ∗− as well as pˉp→Ξˉ∗+Ξ− with various decay modes are investigated. For the exclusive reconstruction of the signal events a full decay tree fit is used, resulting in reconstruction efficiencies between 3% and 5%. This allows high statistics data to be collected within a few weeks of data taking
