Strange 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 کاملScreening Effects in Superfluid Nuclear and Neutron Matter within Brueckner Theory
Effects of medium polarization are studied for 1S0 pairing in neutron and nuclear matter. The screening potential is calculated in the RPA limit, suitably renormalized to cure the low density mechanical instability of nuclear matter. The selfenergy corrections are consistently included resulting in a strong depletion of the Fermi surface. All medium effects are calculated based on the Brueckner...
متن کاملHyperonic Crystallization in Hadronic Matter
We propose a method for analyzing the formation of spatially ordered configurations in hadronic matter, related to the crystallization of the hyperonic sector in a lattice. The method allows the determination of the density ranges where such ordered configurations are energetically favoured with respect to the usual gaseous configurations. This leads to the determination of the parameters of a ...
متن کاملAsymmetric 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 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...
