Abstract
The BM@N (Baryonic Matter at the Nuclotron) is an experiment at the NICA (Nuclotron-based Ion Collider fAcility). The first physics runs were carried out with the collection of experimental data in 2018. The problem of particle identification is necessary for the physical analysis of the matter formed after the collision of the beam with the target. This paper describes identification algorithms based on the method nδ and a variation of the distance method. The algorithms were tested on simulated data, the results are analyzed for efficiency and contaminations.
