On the structure of the relativistic HartreeFock theory
Abstract
Starting from a chargeconjugation symmetric hamiltonian for nucleons and antinucleons interacting via a static twobody force, a "renormalized" HartreeFock (HF) theory for nuclear matter is defined by studying the relation to the HF approximations of the vacuum, the one and the twonucleon problems. The emerging (formal) result for the nuclearmatter binding energy is equivalent to that of the standard relativistic HF theory if suitable effective manybody forces are used. Expanding in terms of NN̄ pair corrections there are, however, deviations in third order if only effective twobody interactions are taken into account. We also derive the expression for the complete (renormalized) secondorder NN̄ pair correction to the nuclearmatter binding energy.
