Abstract

This work is devoted to the search for \(\phi \) (1020) after collisions in the Baryonic Matter at Nuclotron (BM@N) experiment, implemented at the Joint Institute for Nuclear Research (JINR, Dubna). To analyze the effectiveness of the reconstruction algorithms, Monte Carlo simulations of the collision of a 3.9 AGeV Xe beam with a CsI target were used. After reconstruction of the events and selection of candidate pairs, distribution of the invariant mass was obtained and a peak corresponding to \(\phi \) (1020) was identified. The dependence of the reconstruction efficiency of the strange particle on rapidity and transverse momentum was derived.
