Optimization of the Primary Vertex Reconstruction Algorithm for the BM@N Experiments with Regard to Topology of Events

Abstract

BM@N (Baryonic Matter at Nuclotron) is the first working experiment performed on the NICA accelerating complex. It is a fixed target experiment. To this moment there have been seven runs of the experiment, most of which are technical. In 2018 the first run of the experimental facility with physics data collection took place. One of the prerequisites for physics analysis of experimental data is the existence of the primary vertex position estimation. Current report describes the proposed algorithm to reconstruct the primary vertex using the virtual planes method. The results of this algorithm for different targets, beams and trigger conditions are presented. The sensitivity of presented method is considered.
