Hypernuclear Matter with Nijmegen Baryon-Baryon Interaction

Baryon Interactions in Nuclear and Hypernuclear Matter

The production and structure of Λ hypernuclei are investigated in field theoretical models. The production in coherent p+A reactions is investigated by means of a resonance model. Results of exploratory calculations for associated strangeness production are presented for proton reactions on 40Ca. The target single particle wave functions are obtained from DDRH theory with density dependent Dira...

Microscopic baryon-baryon interactions at finite density and hypernuclear structure

In-Medium Baryon Interactions and Hypernuclear Structure

We introduce a microscopic and relativistic theory describing free scattering and finite nuclei for the octet baryons in a consistent quantum field theoretical framework based on Dirac-Brueckner theory and nuclear mean-field. In a first quantitative approach yet still heuristic for dealing with the Λ hyperon the quality of the description of finite (hyper)nuclei based on free meson exchange pot...

Hypernuclear structure with the new Nijmegen potentials

We perform continuous-choice Brueckner-Hartree-Fock calculations of hypernuclear matter, using the recent Nijmegen potentials for hyperon-nucleon and hyperon-hyperon interactions. Single-particle observables of the various hyperons in bulk matter, as well as properties of singleand double-lambda hypernuclei, employing an extended Skyrme-Hartree-Fock scheme, are presented. We find that the poten...

Quark-model Baryon-baryon Interaction and Its Applications to Hypernuclei * )

The quark-model baryon-baryon interaction fss2, proposed by the Kyoto-Niigata group, is a unified model for the complete baryon octet (B8 = N , Λ, Σ and Ξ), which is formulated in a framework of the (3q)-(3q) resonating-group method (RGM) using the spin-flavor SU6 quark-model wave functions and effective meson-exchange potentials at the quark level. Model parameters are determined to reproduce ...
