Nuclear matter EOS with a three-body force
نویسندگان
چکیده
The effect of a microscopic three-body force on the saturation properties of nuclear matter is studied within the Brueckner-Hartree-Fock approach. The calculations show a decisive improvement of the saturation density along with an overall agreement with the empirical saturation point. With the three-body force the symmetry energy turns more rapidly increasing with density, which allows for the direct URCA process to occur in β-stable neutron star matter. The influence of the threebody force on the nuclear mean field does not diminish the role of the ground state correlations. PACS numbers: 25.70.-z, 13.75.Cs, 21.65.+f, 24.10.Cn

The equations of state of spin-polarized nuclear matter and pure neutron matter are studied in the framework of the Brueckner-Hartree-Fock theory including a three-body force. The energy per nucleon EA(δ) calculated in the full range of spin polarization δ = ρ↑−ρ↓ ρ for symmetric nuclear matter and pure neutron matter fulfills a parabolic law. In both cases the spin-symmetry energy is calculate...
متن کاملInterplay of Three-Body Interactions in the EOS of Nuclear Matter
The equation of state of symmetric nuclear matter has been investigated within Brueckner approach adopting the charge-dependent Argonne V18 twobody force plus a microscopic three-body force based on a meson-exchange model. The effects on the equation of state of the individual processes giving rise to the three-body force are explored up to high baryonic density. It is found that the major role...
متن کاملNeutron Star Properties with Nuclear Bhf Equations of State
We study the properties of static and rotating neutron stars adopting non-relativistic equations of state (EOS) for asymmetric nuclear matter based on the Brueckner-Hartree-Fock (BHF) scheme. The BHF calculation, with the continuous choice for the single particle potential, appears to be very close to the full EOS, which includes the three-hole line contribution calculated by solving the Bethe-...
متن کاملEquation of state for nucleonic matter and its quark mass dependence from the nuclear force in lattice QCD.
Quark mass dependence of the equation of state (EOS) for nucleonic matter is investigated, on the basis of the Brueckner-Hartree-Fock method with the nucleon-nucleon interaction extracted from lattice QCD simulations. We observe saturation of nuclear matter at the lightest available quark mass corresponding to the pseudoscalar meson mass ≃469 MeV. Mass-radius relation of the neutron stars is a...
متن کاملMicroscopic nuclear equation of state with three-body forces and neutron star structure
We calculate static properties of non-rotating neutron stars (NS’s) using a microscopic equation of state (EOS) for asymmetric nuclear matter. The EOS is computed in the framework of the Brueckner–Bethe–Goldstone many–body theory. We introduce three-body forces in order to reproduce the correct saturation point of nuclear matter. A microscopic well behaved EOS is derived. We obtain a maximum ma...
