Abstract

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 P ¯¯¯¯¯¯ANDA will provide direct access to final states containing a Ξ¯¯¯¯Ξ pair, for which production cross sections up to μ b are expected in p ¯p reactions. With a luminosity of L=1031 cm−2 s−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, P ¯¯¯¯¯¯ANDA will thus be a hyperon factory. In this study, reactions of the type p ¯p → Ξ¯¯¯¯+ Ξ∗− as well as p ¯p → Ξ¯¯¯¯∗+ 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.
