Abstract By means of the Matsubara imaginary-time Green's function method, we extend the NNπ interaction to finite-temperature and finite-density by summing bubble diagrams. We find that the effective mass of pion increases but the effective NNπ interaction decreases as the density and/or temperature increase.
