Study of Λ-Hyperon Production in Collisions of Heavy Ions with Solid Targets in the BM@N Experiment.

BM@N (Baryonic Matter at Nuclotron) is the first fixed target experiment collecting data at the NICA accelerator. The goal of BM@N physics program is a study of highly compressed nuclear matter in heavy ion beams. The Nuclotron provides heavy ion beams with energies from 2.3 to 4.5 AGeV, which is suitable for studies of strange mesons and multi–strange hyperons produced in nucleus-nucleus collisions close to the kinematic threshold [1]. BM@N expеriment collected first data in 2017 (Run-6) with a carbon beam of 4.0 and 4.5 AGeV kinetic energy with' a set of solid targets: Al, C, Cu, Pb. This paper describes the calculation methodology of the cross sections and yield measurements of the Λ → p + π^– decay channel. [ABSTRACT FROM AUTHOR]
