    "abstract": "A relativistic description of pion-nucleon scattering based on the\nfour-dimensional Bethe-Salpeter equation is presented. The kernel of the\nequation consists of s- and u-channel nucleon and delta pole diagrams, as well\nas rho and sigma exchange in the t-channel. The Bethe-Salpeter equation is\nsolved by means of a Wick rotation, and good fits are obtained to the s- and\np-wave phase shifts up to 360 MeV pion laboratory energy. The coupling\nconstants determined by the fits are consistent with the commonly accepted\nvalues in the literature.",
