Description
One of the priority tasks performed in the BM@N experiment is to classified events into centrality classes. The centrality procedure allows to estimate the initial geometry in heavy ion collisions using the relation between the observable and the impact parameter. The observable is usually the multiplicity of produced particles or the energy of the spectators. In this work, new approaches are proposed to determine the centrality using the spectator nucleon energy from the forward hadron calorimeter FHCal and the sum of charge from the hodoscope. The efficiency of the proposed methods was tested on data from the BM@N experiment for Xe+CsI collisions at a beam energy of 3.8 A GeV.
