Asymmetric Nuclear Matter in the Relativistic Brueckner Hartree Fock approach
We present a calculation of asymmetric nuclear matter properties in a relativistic Brueckner Hartree Fock framework. Following other calculations the components of the self-energies are extracted by projecting on Lorentz invariant amplitudes. It is shown that for asymmetric nuclear matter one needs a sixth invariant. We present a set of invariants which in the limit of symmetric nuclear matter ...
متن کاملStrange nuclear matter within Brueckner-Hartree-Fock theory
We have developed a formalism for microscopic Brueckner-type calculations of dense nuclear matter that includes all types of baryon–baryon interactions and allows to treat any asymmetry on the fractions of the different species (n, p,Λ,Σ−,Σ0,Σ+,Ξ− and Ξ0). We present results for the different single–particle potentials focussing on situations that can be relevant in future microscopic studies o...
متن کاملAsymmetric Nuclear Matter from Extended Brueckner-Hartree-Fock Approach
The properties of isospin-asymmetric nuclear matter have been investigated in the framework of the extended Brueckner-Hartree-Fock approximation at zero temperature. Selfconsistent calculations using the Argonne V14 interaction are reported for several asymmetry parameters β = N−Z A ranging from symmetric nuclear matter to pure neutron matter. The binding energy per nucleon fulfills the β law i...
متن کاملNucleon effective masses within the Brueckner-Hartree-Fock theory: Impact on stellar neutrino emission
We calculate the effective masses of neutrons and protons in dense nuclear matter within the microscopic Brueckner-Hartree-Fock many-body theory and study the impact on the neutrino emissivity processes of neutron stars. We compare results based on different nucleon-nucleon potentials and nuclear three-body forces. Useful parametrizations of the numerical results are given. We find substantial ...
متن کاملThe properties of nuclear matter with lattice NN potential in relativistic Brueckner-Hartree-Fock theory
We study the properties of nuclear matter with lattice nucleon-nucleon (NN) potential in the relativistic Brueckner-Hartree-Fock (RBHF) theory. To use this potential in such a microscopic many-body theory, we firstly have to construct a one-boson-exchange potential (OBEP) based on the latest lattice NN potential. Three mesons, pion, σ meson, and ω meson, are considered. Their coupling constants...
