Track reconstruction algorithms for CBM — •Andrey Lebedev for the CBM collaboration — GSI, Darmstadt, Germany — JINR, Dubna, Russia

The Compressed Baryonic Matter (CBM) experiment at the future FAIR accelerator at Darmstadt will perform a comprehensive measurement of hadron and lepton production in heavy-ion collisions at 8-45 AGeV beam energies.

In this contribution, a description, results and the current status of the track-finding routines developed for the Transition Radiation Detector (TRD) and muon detector (MuCh) of the CBM experiment are presented. A generalized algorithm for track-finding is described. It is based on the Kalman Filter and track following methods. For the TRD two different approaches have been used: a standalone TRD track-finder (using only TRD information), and an algorithm based on the information from tracks, found in preceding detectors. For the MuCh detector, which consists of a sequence of several absorber and detector layers, vertex tracks have been used as seeds for track reconstruction. Performances of algorithms are presented. A detector layout study has been performed in order to optimize the detector setup while keeping high reconstruction efficiency.
