Query: Static properties of nuclear matter within the Boson Loop Expansion   The use of the Boson Loop Expansion is proposed for investigating the static
properties of nuclear matter. We explicitly consider a schematic dynamical
model in which nucleons interact with the scalar-isoscalar sigma meson. The
suggested approximation scheme is examined in detail at the mean field level
and at the one- and two-loop orders. The relevant formulas are provided to
derive the binding energy per nucleon, the pressure and the compressibility of
nuclear matter. Numerical results of the binding energy at the one-loop order
are presented for Walecka's sigma-omega model in order to discuss the degree of
convergence of the Boson Loop Expansion.
