Abstract

The properties of nuclear matter are studied in the cut-off field theory. It is found that, under the Hartree approximation, the small cut-off makes the equations of state hard, especially at higher densities. The theory is modified in the framework of the renormalization group methods with arbitrary cut-off Λ^′. It is found that the expansion in terms of the σ meson field is more favorable than the naive expansion of the inverse of Λ^′, when we do not use very large Λ^′.
