Description

The main goal of the CBM experiment is a comprehensive study of the QCD phase diagram in a region of Quark-Gluon Plasma (QGP) and possible phase transition to the QGP phase. One of the expected signals of QGP formation is enhanced strangeness production. Being abundant particles, Σ+ and Σ- carry out a large fraction of produced strange quarks. Therefore, reconstruction of Σ hyperons completes the picture of strangeness production. Σ+ and Σ- have all decay modes with at least one neutral daughter. However, these particles have a lifetime sufficient to be registered by the tracking system: cτ = 2.4 cm for Σ+ and cτ = 4.4 cm for Σ-. For their identification the missing mass method is proposed to be applied. The method allow to obtain a large efficiency in the level of several percents together with a high signal to background level.
