Baryon-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.

Baryon-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...

Meson-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...

Baryon-baryon interactions in large NC chiral perturbation theory.

Interactions of two baryons are considered in large NC chiral perturbation theory and compared to the interactions derived from the Skyrme model. Special attention is given to a torus-like configuration known to be present in the Skyrme model.
