Understanding the excitation pattern of baryons is indispensable for the understanding of non-perturbative QCD. Up to now only the nucleon excitation spectrum has been subject to systematic experimental studies, in contrast very little is known on excited states of double or triple strange baryons. A better knowledge of the baryon spectrum in the double and triple strange sector is however important to scrutinize the models developed using data on N* and Δ states. In studies of antiproton-proton collisions, the P̅ANDA experiment is well-suited for a comprehensive baryon spectroscopy program in the multi-strange and charm sector.
For final states containing a Ξ‾ Ξ̅⁺ pair, cross sections of the order of μb are expected, corresponding to production rates of ~10⁶ /d at a luminosity L = 10³¹ cm‾² s‾¹. The present thesis focuses on excited Ξ states and investigates the possibility to reconstruct the reaction p̅p -> Ξ̅⁺Ξ*‾ and its charged conjugate channel with the P̅ANDA detector. Furthermore, first steps towards a partial wave analysis of the Ξ̅⁺Λ K‾ and Ξ‾Λ̅ K⁺ final states are presented.
