CBM performance for strange hyperon flow measurements — •Oleksii Lubynets1, 2, 3, Ilya Selyuzhenkov1, 4, and Viktor Klochkov1, 2 for the CBM collaboration — 1GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt, Germany — 2Goethe Universität Frankfurt, Frankfurt am Main, Germany — 3Frankfurt Institute for Advanced Studies, Frankfurt am Main, Germany — 4National Research Nuclear University (Moscow Engineering Physics Institute), Moscow, Russia

The main goal of the CBM experiment is to study highly compressed baryonic matter produced in collisions of heavy ions. SIS100 accelerator at FAIR will give a possibility to investigate the QCD matter at temperatures about 120 MeV and net baryon densities 5-6 times larger than a nuclei density. Strange hyperons produced in the dense phase of the heavy-ion collision provide information about the equation of state of the QCD matter. The measurement of their anisotropic flow is important for understanding the evolution of the QCD matter.

In this work the status of the CBM performance for strange particle anisotropic flow measurement is presented. Flow coefficients are calculated relative to the spectator plane estimated with the CBM Projectile Spectators Detector. Strange hyperons decay within the CBM detector volume and are reconstructed via their decay topology. Kalman Filter Particle Finder package is a very powerful tool, which allows to reconstruct decays with high efficiency. In the current work its simplified version, the KF Simple, is used to optimize selection criteria of the strange hyperon reconstruction and for CBM flow performance study.
