Importance of Baryon-baryon Coupling in Hypernuclei
The ΛN − ΣN coupling in Λ–hypernuclei and ΛΛ − ΞN coupling in ΛΛ– hypernuclei produce novel physics not observed in the conventional, nonstrange sector. Effects of Λ ↔ Σ conversion in ΛH are reviewed. The role of ΛN − ΣN coupling suppression in the A = 4, 5 Λ–hypernuclei due to Pauli blocking is highlighted, and the implications for the structure of 10 ΛB are explored. Suppression of ΛΛ − ΞN co...
متن کاملQuark-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 ...
متن کاملMeson-baryon interactions and baryon resonances
Meson-baryon interactions are the fundamental building blocks to study the structures of baryon resonances and meson properties in few-body nuclear systems. We review the recent progress in the investigation of the meson-baryon interaction in the strangeness S “ ́1 sector and the structure of the Λp1405q resonance. In particular, we present an attempt to construct a realistic KN-πΣ interaction i...
متن کاملBaryon-Baryon Interactions and the Eightfold Way
ECENTLY, Gell-Mann' and Ne'eman have independently proposed a scheme, called the eightfold way, in which the eight baryons (ftT, A., Z, and ) are assumed to form a supermultiplet, degenerate in the limit of a certain symmetry, and split into the familiar isotopic multiplets by a dynamical interaction. The symmetry is called unitary symmetry and the relevant group is the group of unitary unimodu...
متن کاملBaryon-Baryon Interactions from the Lattice
I discuss the latest progress in calculating baryon-baryon interactions with lattice QCD. The latest results from the NPLQCD collaboration for nucleon-nucleon scattering along with preliminary calculations of hyperon-nucleon scattering are presented.
