ΛΛ−ΞN−ΣΣcoupling inHeΛΛΛ6with the Nijmegen soft-core potentials

The Nijmegen Potentials

A review is given of the various Nijmegen potentials. Special attention is given to some of the newest developments, such as the extended soft-core model, the high-quality potentials, and the Nijmegen optical potentials for NN.

Hypernuclear structure with the Nijmegen ESC08 potentials

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...

Liquid-liquid phase transitions for soft-core attractive potentials.

Using event-driven molecular dynamics simulations, we study a three-dimensional one-component system of spherical particles interacting via a discontinuous potential combining a repulsive square soft core and an attractive square well. In the case of a narrow attractive well, it has been shown that this potential has two metastable gas-liquid critical points. Here we systematically investigate ...

4 ΛΛ bond energy from the Nijmegen potentials

The ΛΛ bond energy ∆B ΛΛ in ΛΛ hypernuclei is obtained from a G-matrix calculation which includes the coupling between the ΛΛ, ΞN and ΣΣ channels, as well as the effect of Pauli blocking to all orders. The Nijmegen NSC97e model is used as bare baryon-baryon interaction in the strangeness S = −2 sector. The ΛΛ-ΞN coupling increases substantially the bond energy with respect to the uncoupled ΛΛ c...
