Abstract:

At zero-density, meson-nucleon vertex corrections are studied in the σ-ω model with cutoff. It is shown that the properties of the vertex corrections are somewhat different from those described by the ordinary renormalization procedures when the cutoff is small (< 5 GeV). The low-energy effective Lagrangian is constructed in the framework of the renormalization group method. Weak tensor and derivative couplings of meson-nucleon interactions may be needed in the low-energy effective theory of mesons and nucleons.
