Abstract.
We present a new two-body finite-range and momentum-dependent but
density-independent e
ff
ective interaction, which can be interpreted as a regularized zero-
range force. We show that no three-body or density-dependent terms are needed for a
correct description of saturation properties in infinite matter, that is, on the level of low-
energy density functional, the physical three-body e
ff
ects can be e
ffi
ciently absorbed in
e
ff
ective two-body terms. The new interaction gives a satisfying equation of state of
nuclear matter and opens up extremely interesting perspectives for the mean-field and
beyond-mean-field descriptions of atomic nuclei.
