Time based track reconstruction in the CBM experiment — •Timur Ablyazimov^{1, 2} and Volker Friese¹ for the CBM collaboration — ¹GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt — ²LIT JINR, Dubna, Russia

The Compressed Baryonic Matter experiment (CBM) at FAIR is designed to cope with high track-densities and extreme interaction rates of up to 10 MHz. Because of the interaction rates events are unavoidably overlap in time. Accordingly the reconstruction in the CBM experiment becomes possible only taking into account time measurements. This approach was first implemented for the Silicon Tracking System (STS), which is the main tracking detector of the CBM experimental setup. Now the time based reconstruction concept is being extended to other detectors, whose measurements can be used for STS reconstructed tracks extrapolation through the CBM setup.

We will present that status of the time-based simulation and reconstruction for the Time of Flight (TOF) detector. This is because of its excellent time resolution and crucial importance for determining the physical properties of the particles and the particles identification. We are developing approaches for time based hit finding in TOF and for using them for STS tracks extrapolation to the TOF detector.
