标题： Double-Lambda hypernuclei within a Skyrme-Hartree-Fock approach

摘要： 我们扩展了之前成功用于描述单个$\Lambda$超核的 Skyrme-Hartree-Fock (SHF) 方法，以研究双$\Lambda$超核的结合能和$\Lambda \Lambda$键能。 核子-核子 ($NN$) 和$\Lambda$-核子 ($\Lambda N$) 相互作用来自于我们之前的研究。 对于$\Lambda \Lambda$力，已使用文献中可用的几种类似 Skyrme 的势能。 我们讨论了计算得到的$\Lambda \Lambda$结合能和键能对$\Lambda \Lambda$和$\Lambda N$力参数的敏感性。 发现现有的$\Lambda \Lambda$超核数据无法区分我们使用的各种$\Lambda \Lambda$力参数集。 然而，它们对于我们在之前工作中确定的$\Lambda N$势的一个特定集合显示出一定的选择性。 显示英文摘要

摘要： We extend our Skyrme-Hartree-Fock (SHF) approach, which was used earlier to describe successfully the single-$\Lambda$ hypernuclei, to investigate the binding and the $\Lambda \Lambda$ bond energies of the double-$\Lambda$ hypernuclei. The nucleon-nucleon ($NN$) and $\Lambda$-nucleon ($\Lambda N$) interactions are taken from our previous study. For the $\Lambda \Lambda$ force several Skyrme-like potentials available in the literature have been used. We discuss the sensitivity of the calculated $\Lambda \Lambda$ binding and bond energies to the $\Lambda \Lambda$ and $\Lambda N$ force parameters. It is found that the existing $\Lambda \Lambda$ hypernuclear data do not allow to distinguish between various $\Lambda \Lambda$ force parameter sets used by us. However, they show some selectivity for a particular set of the $\Lambda N$ potential determined in our previous work.
