Study of the Influence of Various Factors on the Quality of Reconstruction of Λ and \(K_{S}^{0}\) in the BM@N Experiment Using Monte Carlo Simulation
This work is devoted to the search for lambda hyperons and short-lived neutral kaons born in nuclear collisions in the Baryonic Matter at Nuclotron (BM@N) experiment, implemented at the Joint Institute for Nuclear Research (JINR, Dubna). To analyze the influence of different sources on the effectiveness of strange particle reconstruction algorithms, Monte Carlo simulations of the collision of a 3.9 AGeV Xe beam with a CsI target were used. After reconstruction of events and selection of candidate pairs, distributions of invariant masses were obtained and peaks corresponding to lambda hyperons and neutral kaons were identified. An analysis of the impact of each of the sources on the reduction of reconstruction efficiency was performed.
