  "abstract": "A model for $\\pi$N scattering and $\\eta$-meson production in the S$_{11}$ channel is presented. The model includes $\\pi$N-scattering Born terms as well as the N$^*${} resonances S$_{11}$(1535) and S$_{11}$(1610). The $T$-matrix is computed in the $K$-matrix approximation. The parameters of the model are determined by fitting the elastic $\\pi$N-scattering $T$-matrix to empirical data. We find an excellent fit for all energies up to $\\sqrt{s}$ = 1.75 GeV. Furthermore, a good description of the cross section for $\\pi^- + p \\rightarrow \\eta + n$ is obtained without further adjustment of parameters.",
