Reconstruction of hypernuclei in CBM — •Maksym Zyzak1, Iouri Vassiliev1, and Ivan Kisel1,2,3 for the CBM collaboration — 1GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt, Germany — 2Göthe-Universität Frankfurt, Frankfurt am Main, Germany — 3Frankfurt Institute for Advanced Studies, Frankfurt am Main, Germany

The main goal of the CBM experiment is to study highly compressed baryonic matter produced in the collisions of heavy ions. According to modern theories a complex structure of the QCD matter is predicted in the energy region of the SIS100 accelerator. To successfully fulfil its wide and challenging physics program CBM will study all relevant observables. One of them are hypernuclei, which are believed to be sensitive probes of the newly created matter. They will allow investigation of the equation of state of the highly compressed baryonic matter, hyperon-nucleon and hyperon-hyperon interactions.

The maximum yields of hypernuclei are predicted to be at CBM energies. Thus, with its unprecedented interaction rate of 107 Hz CBM will be able to perform high-precision measurement of hypernuclei containing one Λ particle like Λ3H, Λ4H, Λ4He, Λ5He, etc.  and even double-Λ hypernuclei like ΛΛ4H or ΛΛ6He. Results of the feasibility studies on the reconstruction of hypernuclei in the CBM experiment are presented and discussed.
