    "abstract": "The variational approach, used by Feynman in the study of the polaron\nproblem, is generalized to treat a system of N non-relativistic particles\ninteracting with scalar and vector mesons. After integrating out the meson\nfields in the path integral formulation we perform a variational calculation\nfor the effective N-body two-time action to obtain the energy and the mass of\nthe system. The interplay of self energies and exchange terms in attaining\nbinding and saturation is examined. We estimate the size of the particles in\nthe medium and give the mean number of mesons as a function of N.",
