Relativistic Mean – Field Calculations of Λ and Σ Hypernuclei ∗ February 9 , 2008
نویسنده
چکیده
Single–particle spectra of Λ and Σ hypernuclei are calculated within a relativistic mean–field theory. The hyperon couplings used are compatible with the Λ binding in saturated nuclear matter, neutron-star masses and experimental data on Λ levels in hypernuclei. Special attention is devoted to the spin-orbit potential for the hyperons and the influence of the ρ-meson field (isospin dependent interaction). PACS number: 21.80.+a

Double-Λ hypernuclei in the relativistic mean-field theory
We study the properties of double-Λ hypernuclei in the relativistic mean-field theory, which has been successfully used for the description of stable and unstable nuclei. With the meson-hyperon couplings determined by the experimental binding energies of single-Λ hypernuclei, we present a self-consistent calculation of double-Λ hypernuclei in the relativistic mean-field theory, and discuss the ...

The Density Dependent Relativistic Hadron Field (DDRH) theory, previously introduced and applied to isospin nuclei, is extended to hypernuclei by including the octet hyperons. Infinite matter Dirac-Brueckner theory for octet baryons and the derivation of in-medium DDRH baryon-meson vertices is discussed. From the properties of Dirac-Brueckner interactions it is found that hyperon and nucleon se...
متن کاملHypernuclei and in-medium chiral dynamics
A recently introduced relativistic nuclear energy density functional, constrained by features of low-energy QCD, is extended to describe the structure of hypernuclei. The density-dependent mean field and the spin-orbit potential of a Λ-hyperon in a nucleus, are consistently calculated using the SU(3) extension of in-medium chiral perturbation theory. The leading long-range ΛN interaction arises...
متن کاملA particle-hole model approach for hypernuclei
A particle-hole model is developed to describe the excitation spectrum of single Λ hypernuclei and the possible presence of collective effects is explored by making a comparison with the mean-field calculations. Results for the spectra of 12 Λ C , 16 Λ O , 40 Λ Ca , 90 Λ Zr and 208 Λ Pb hypernuclei are shown. The comparison with the available experimental data is satisfactory. We find that coll...
متن کاملRelativistic mean - field description of light Λ hypernuclei with large neutron excess
The Relativistic Hartree Bogoliubov model in coordinate space, with finite range pairing interaction, is applied to the description of Λ-hypernuclei with a large neutron excess. The addition of the Λ hyperon to Ne isotopes with neutron halo can shift the neutron drip by stabilizing an otherwise unbound core nucleus. The additional binding of the halo neutrons to the core originates from the inc...
