In experiments like MPD, that study behaviour of particles, it is important to correctly identify registered particles. One problem is the identification of particles that generate signal in detector. Second is the reconstruction of baryons, that have life span too short to reach detectors. All of this is important in studying strong interactions between different baryon types.

A new approach to particle identification based on four methods including:
- dE/dx($p_{total}$)
- $\beta(p_{total)}$
- $m^2(p_{total)}$
- $m^2(dE/dx)$
This method takes advantage of Monte Carlo data to create templates for aforementioned distributions. The templates are then used to determine given track's identity.
