A many body theory is developed where the Hilbent space is allowed to contain states of nucleons and mesons. The basis of the theory is the treatment of a field-theoretical Hamiltonian within noncovariant perturbation theory. Only diagrams corresponding to a one-boson exchange (OBE) are taken into account. First, the two-body scattering problem is developed, and this yields a scattering equation corresponding to that of Kadyshevsky. Then the theory is applied to the binding energy problem of nuclear matter in the two hole line approximation with a choice of the single-particle spectrum taken analogously to the Brueckner-Bethe theory. The resulting equations contain meson current corrections, which are physically interpreted. The standard Brueckner theory with static OBE forces is obtained in an adiabatic limit.
