Fast reconstruction of multi-strange hyperons in the CBM experiment — •Iouri Vassiliev¹, Ivan Kisel^1,2, and Maxim Zyzak^1,2,3 for the CBM collaboration — ¹GSI, Helmholtzzentrum für Schwerionenforschung Darmstadt, Germany — ²Institute for Advanced Studies, Frankfurt am Main, Germany — ³Goethe University Frankfurt am Main, Frankfurt am Main, Germany

The main goal of the CBM experiment is to study the behaviour of nuclear matter at very high baryonic density in which the transition to a deconfined and chirally restored phase is expected to happen. One of the promissing signatures of this new state is the enhanced production of multi-strange particles, therefore the reconstruction of multi-strange hyperons is essential for the understanding of the heavy ion collision dynamics. Another experimental challenge of the CBM experiment is online selection of open charm particles via the displaced vertex of the hadronic decay, charmonium and low mass vector mesons in the environment of a heavy-ion collision. This task requires fast and efficient track reconstruction algorithms, primary vertex finder and particles finder. Results of feasibility studies of the multi-strange hyperons in the CBM experiment will be presented.
