Analysis of Hypernuclei in Simulated Data of the BM@N Experiment

This work is devoted to the study of the simplest hypernuclei, namely $$_{\Lambda }^{3}{\text{H}}$$ and $$_{\Lambda }^{4}{\text{H}}$$ , in the BM@N experiment. They may be one of the possible markers of the phase transition from nuclear matter to quark-gluon plasma in high-energy ion collisions. Reconstruction efficiency of two-body $${{\pi }^{ - }}$$ ecays of these hypernuclei was estimated using simulated data based on DCM-SMM nuclear interaction model and a realistic description of the BM@N spectrometer. A procedure to optimize significance of the observed signal of hypernuclei decays is developed and presented.
