Abstract
The Hades spectrometer is a versatile detector device operating at the SIS18 synchrotron at GSI Darmstadt with a vital list of results on strangeness production including Λ(1405) and Σ(1385) exclusive production cross-sections, Λ polarization, Λ-p correlation and Kaons in-medium. With the upgrade of the SIS18 synchrotron for the FAIR facility and the upgrade of HADES with a new Forward Detector, the experiment will have an unique opportunity to study also excited hyperon states. Among others, production and electromagnetic decays of excited Λ and Σ hyperons states, Ξ− cascade spectroscopy and - production and correlation are planned. We have studied the reconstruction feasibility using two benchmark channels of Λ(1520) → Λe+e− Dalitz decay and exclusive Ξ− production in pp→Ξ−K+K+p reaction. The Forward Detector consisting of a forward tracker made of PANDA straw tubes prototypes and a RPC time of flight detector will enlarge HADES acceptance to forward angles (0.5-7°), important for Λ tagging. The magnetic field-free forward region will require employment of kinematical refit and neural networks analysis methods to perform particle identification. In this contribution highlights of strangeness production in p-p and p-A reactions will be presented together with perspectives for the future hyperon programme.
