Analysis of Reconstruction Efficiency of Λ and \(K_{{\text{S}}}^{0}\) for the BM@N Experiment Using Monte Carlo Generated Events

Abstract

This work is devoted to the search for lambda hyperons and short-lived neutral kaons 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 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. The dependence of the reconstruction efficiency of strange particles on rapidity and transverse momentum was derived.
