Event reconstruction in the CBM experiment

A typical central Au+Au collision in the CBM experiment (GSI, Germany) will produce up to 700 tracks in the inner tracker. The large track density together with the presence of a non-homogeneous magnetic field make reconstruction of events complicated. ular automaton method is used to reconstruct tracks in the inner tracker. Track and vertex fitting is done using the Kalman filter technique. A special analytic formula has been derived for fast track extrapolation in a non-homogeneous magnetic field. A standalone ring finding in the RICH detector is based on the elastic net method. Results of tests of the reconstruction procedure are presented.
