The ¹ S₀ pairing of symmetric nuclear matter is discussed in the frame work of relativistic nuclear theory with Dyson-Schwinger equations (DSEs). The in-medium nucleon and meson propagators are treated in a more self-consistent way through meson polarizations. The screening effects on mesons due to in-medium nucleon excitation are found to reduce the ¹S₀ pairing gap and shift remarkably the gap peak to low density region.
