    "abstract": "The Schwinger-Dyson equations for the nucleon and meson propagators are\nsolved self-consistently in an approximation that goes beyond the Hartree-Fock\napproximation. The traditional approach consists in solving the nucleon\nSchwinger-Dyson equation with bare meson propagators and bare meson-nucleon\nvertices; the corrections to the meson propagators are calculated using the\nbare nucleon propagator and bare nucleon-meson vertices. It is known that such\nan approximation scheme produces the appearance of ghost poles in the\npropagators. In this paper the coupled system of Schwinger-Dyson equations for\nthe nucleon and the meson propagators are solved self-consistently including\nvertex corrections. The interplay of self-consistency and vertex corrections on\nthe ghosts problem is investigated. It is found that the self-consistency does\nnot affect significantly the spectral properties of the propagators. In\nparticular, it does not affect the appearance of the ghost poles in the\npropagators.",
