Abstract: | The properties and temperature behavior of the π and σ bound states are studied in the framework of the nonlocal model with
a separable interaction kernel, based on the quark Dyson-Schwinger and meson Bethe-Salpeter equations. M
π(T), f
π(T), M
σ(T), and Γσ → ππ(T) are considered above and below the deconfinement and chiral restoration transitions.
