The exclusive production of hyperon-antihyperon pairs close to their production threshold in p-nucleus collisions offers a unique and hitherto unexplored opportunity to elucidate the behavior of antihyperons in nuclei. Calculations find a substantial sensitivity of the transverse momentum correlations of coincident ΛΛ-pairs to the assumed depth of the Λ-potential. [Lorente et al., Phys. Lett. B 749 (2015) 421]
The facility for antiproton and ion research (FAIR) currently under construction in Darmstadt, Germany will offer a high quality, high luminosity p-beam to be used in experiments. Starting from 2026 the PANDA experiment at FAIR will begin with its "day-1" setup where a partial setup of the detector and reduced luminosity will be available. Because of the high cross section for the process and the simplicity of the experimental method the "day-1" setup can be used to measure these momentum correlations.
We present our current feasibility study of the event reconstruction for the reaction p+20Ne→ΛΛ close to production threshold in the PANDA "day-1" setup. The GiBUU framework is used to simulate the primary interaction and GEANT4/GENFIT2 for propagation, tracking and reconstruction. The detector efficiency and resolution are being studied and the observable momentum correlations calculated.
