Due to the lack of experimental data, our knowledge on the excitation spectrum of double-strange baryons is very poor, however very important for understanding QCD in the non-perturbative regime. While within SU(3) symmetry the Xi spectrum should have as many states as the N and Delta spectrum together, only few Xi* states are established, most of them without spin-parity assignment. Thanks to the pbar-p entrance channel and the large detector acceptance for both charged and neutral particles, the PANDA experiment is the ideal place for Xi spectroscopy. An important part of the PANDA physics program is therefore devoted to the study of the Xi spectrum. Results of feasibility studies of identifying Xi* states in the final states Xibar+ L K-, Xibar+ Xi- pi0, and Xibar+ Xi- pi+ pi- will be reported, and the perspective of studying further decay modes will be discussed.
