“…potentials are much less attractive than the nucleonic ones, reflecting the weaker strength of the NY compared to the NN potentials. Within the ESC08 model, the well-depths U (k = 0) in normal nuclear matter of the , , and hyperons are, respectively, −39, +16, −8 MeV, and thus in reasonable agreement with current experimental estimates of these quantities [20,21]. The partial wave decompositions of these values are given in Table III which also lists explicitly the contributions of the different (isospin) channels according to Eqs.…”

We perform Brueckner-Hartree-Fock calculations of hypernuclear matter employing the recent Nijmegen extended soft-core 08 hyperon-nucleon and hyperon-hyperon potentials. The results are used in a generalized Skyrme-Hartree-Fock model to calculate the properties of single-and double-hypernuclei. Based on those results, estimates of the effects of hypernuclear three-body forces and other corrections are made.

“…This result agrees with theoretical predictions for in nuclear matter obtained in the model D of the Nijmegen group [44]. However, the missing-mass spectra of a double-charge exchange reaction on a target have suggested the well depth of 14-16 MeV ( MeV MeV) [45], [46]. Data related to the -nucleon interaction are controversial.…”

This paper gives an overview of the model of a neutron star with non-zero strangeness constructed within the framework of the nonlinear realization of the chiral symmetry. The emphasis is put on the physical properties of the matter of a neutron star as well as on its internal structure. The obtained solution is particularly aimed at the problem of the construction of a theoretical model of a neutron star matter with hyperons that will give high value of the maximum mass.

“…The analyses of the (π − , K + ) reaction data on medium to heavy nuclei (Noumi et al 2002) performed in Harada & Hirabayashi (2006) and Kohno et al (2006) revealed a moderately repulsive Σ-nuclear potential in the nuclear interior of around 10-40 MeV, while the fits to Σ − atomic data (Friedman & Gal 2007) indicate a clear transition from an attractive Σ potential in the surface, to a repulsive one in the interior, although the size of the repulsion cannot be precisely determined. As for the strangeness −2 systems, the Nagara event (Takahashi et al 2001) and other experiments providing consistency checks established the size of the ΛΛ interaction to be mildly attractive, (Dover & Gal 1983), while the missing-mass spectra of the -+ K K , ( ) reaction on a 12 C target suggest a milder attraction of −20 MeV (Fukuda et al 1998) or ∼−14±2 MeV (Khaustov et al 2000). These values are compatible with the recent analysis of the nuclear emulsion event KISO, claiming to have observed a nuclear bound state of the Ξ − -14 N system with a binding energy of 4.38±0.25 MeV (Nakazawa et al 2015).…”

We obtain a new equation of state for the nucleonic and hyperonic inner core of neutron stars that fulfils the 2 M e observations as well as the recent determinations of stellar radii below 13 km. The nucleonic equation of state is obtained from a new parameterization of the FSU2 relativistic mean-field functional that satisfies these latest astrophysical constraints and, at the same time, reproduces the properties of nuclear matter and finite nuclei while fulfilling the restrictions on high-density matter deduced from heavy-ion collisions. On the one hand, the equation of state of neutron star matter is softened around saturation density, which increases the compactness of canonical neutron stars leading to stellar radii below 13 km. On the other hand, the equation of state is stiff enough at higher densities to fulfil the 2 M e limit. By a slight modification of the parameterization, we also find that the constraints of 2 M e neutron stars with radii around 13 km are satisfied when hyperons are considered. The inclusion of the high magnetic fields present in magnetars further stiffens the equation of state. Hyperonic magnetars with magnetic fields in the surface of ∼10 15 G and with values of ∼10 18 G in the interior can reach maximum masses of 2 M e with radii in the 12-13 km range.
