Magnetic moments of the Λ(1405) and Λ(1670) resonances

By using techniques of unitarized chiral perturbation theory, where the Λ(1405) and Λ(1670) resonances are dynamically generated, we evaluate the magnetic moments of these resonances and their transition magnetic moment. The results obtained here differ appreciably from those obtained with existing quark models. The width for the Λ(1670) → Λ(1405)γ transition is also evaluated leading to a bran...

Double Λ Hypernuclei and the Λ-λ Interaction. *

We approximate the double Λ hypernuclei by systems composed by two interacting Λ’s moving in the mean field potential created by the nuclear cores. The Λ-core potentials are adjusted to reproduce the binding energies of the corresponding single Λ hypernuclei [1]. A σ-ω meson exchange potential [2] is used for the Λ-Λ interaction. We apply both the Hartree-Fock (HF) and variational approximation...

Shell-Model Description of Λ Hypernuclei

Empirical data on the spectra of light hypernuclei, especially the data from recent γ-ray experiments, is used to constrain the parameters which govern the p N s Λ and p N p Λ two-body matrix elements that enter into shell-model calculations.
