A method to go beyond the Hartree-Fock approximation for the many-body system is developed for the N-Fermion system with two-body interaction acting on the anti-parallel spin particles. The variational energy can be shown to be related to the usual sum of random phase approximation contributions (ring diagram sum) with propagators modified by ring diagrams. Only the formal expressions for the energy were derived in this article, leaving further exploration for later publication.
