Description

BM@N (Baryonic Matter at Nuclotron) is the first experiment to be realized at the accelerator complex of NICA-Nuclotron at JINR (Dubna). The aim of the experiment is to study interactions of relativistic heavy ion beams with a kinetic energy from 1 to 4.5 AGeV with fixed targets.
In the report an algorithm for global tracks reconstruction in the BM@N experiment are described. The core of the global track is the track inside the magnet, to which are added upstream and downstream tracks.
The results of the proposed algorithm working for both the BM@N experiment and its extension SRC program are presented. Matching efficiency and residuals are shown. Influence of global matching procedure on quality of momentum reconstruction and other parameters of a track are presented.
