Abstract: 

The nonlinear system of non-markovian type kinetic equations, describing the particles production with varying masses in framework of Nambu–Jona-Lasinio model is investigated for the case of π-meson production by σ-meson decay in hot and dense nuclear matter. The π-meson enhancement in a low-momentum region due to additional σ-mesons creation via intertial mechanism using the nonlinear dependence of sigmas mass from the temperature in equation of state in vicinity of mσ ≈ 2mπ is calculated.
