Hypernuclear structure with the new Nijmegen potentials
نویسنده
چکیده
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 potentials tend to overbind the single hypernuclei and strongly underbind the double hypernuclei.

Faddeev - Yakubovsky calculations for light ΛΛ hypernuclei
New Faddeev-Yakubovsky calculations are reported for 6 ΛΛ He and 10 ΛΛ Be in terms of clusters of α's and Λ's, using ΛΛ s-wave potentials motivated by several of the Nijmegen model interactions. The self consistency of the ΛΛ hypernuclear world data for these species is discussed. The newly reported 6 ΛΛ He event is found to be compatible with ΛΛ interaction strengths provided by the Nijmegen s...

متن کاملHyperon-hyperon interactions with the Nijmegen ESC08 model
We discuss the properties of the hyperon-hyperon interactions in the recent Nijmegen ESC08 potential, in particular the importance of the coupled-channel structure and related existence of bound states. Brueckner-Hartree-Fock calculations of hypernuclear matter employing these interactions are presented and the structure of hyperon (neutron) stars within this approach is computed. Low maximum m...

We describe full-coupled-channel ab initio calculations among the octet baryons for S = −2 s-shell hypernuclei, 4 ΛΛH, 5 ΛΛH and 6 ΛΛHe. The wave function includes ΛΛ, ΛΣ, NΞ and ΣΣ channels. Minnesota NN , D2 Y N and Nijmegen model D simulated Y Y interactions are used. This is the first attempt to explore the few-body problem of the full-coupled channel scheme for A = 4−6, S = −2 multistrange...
