CBM performance for the measurement of (multi)strange hadrons' anisotropic flow in Au+Au collisions at FAIR — •Oleksii Lubynets^{1, 2} and Ilya Selyuzhenkov¹ for the CBM collaboration — ¹GSI Helmholtzzentrum für Schwerionenforschung — ²Goethe-Universität Frankfurt am Main

The main goal of the CBM experiment is to study highly compressed baryonic matter produced in collisions of heavy ions. The SIS-100 accelerator at FAIR will enable investigation of the QCD matter at temperatures up to about 120 MeV and net baryon densities 5-6 times larger than that of the normal nuclear matter. Hyperons produced during the dense phase of a heavy-ion collision provide information about the equation of state of the QCD matter. The measurement of (multi)strange hyperons' anisotropic flow is important for understanding the dynamics and evolution of the QCD matter created in the collision.

Performance studies for strange hadrons anisotropic flow measurement with the CBM experiment at FAIR will be presented. Strange hadrons are reconstructed via their decay topology using Kalman Filter algorithm methods. Directed flow of strange hadrons is calculated as a function of rapidity, transverse momentum and collision centrality. The effects due to non-uniformity of the CBM detector response in the azimuthal angle, transverse momentum and rapidity are corrected using the QnTools analysis package. The CBM performance is compared with that of the STAR experiment and projections for statistical uncertainties with high statistics data at CBM are presented.
