multi-strange hyperons triggering at SIS 100 — •hamda cherif for the CBM collaboration — Göethe Universität Frankfurt am Main

The Compressed Baryonic Matter (CBM) project at the future facility FAIR will be a dedicated heavy ion experiment operating in fixed target mode at beam energies up to 11A GeV for ions delivered by SIS 100 accelerator. The experimental challenge is to identify hadrons and to select events containing multi-strange hyperons in an environment with up to 1000 charged particles per central collision at reaction rates of up to 10 MHz. A strategy for online event selection for multi-strange hyperons (such as Ξ- , Ξ+, Ω- and Ω+) is developed based on simulated data using the identification of daughter particles in ToF detector and the decay topology in STS detector. The selection strategy developed for Au+Au collision at 10A GeV and extended to lower energies available at SIS100 will be presented.
