标题： Role of Lambda N and Lambda NN interaction parameters on binding energy of Lambda H4 and Lambda H4*

摘要： 对两个超核系统$_\Lambda^4$H 和$_\Lambda^4$H$^*$进行了变分蒙特卡洛研究，以计算结合能。对于所研究的这两个超核系统，采用了不同的势模型来描述这些超核系统中的相互作用。在我们的研究中使用了 ArgonneV$_{18}$NN、Urbana IX NNN 和经验性的$\Lambda$N 和$\Lambda$NN 势。我们的势模型基于我们之前对不同双 Λ 超核系统的相关研究。从我们的结果来看，涉及超子-核子参数，即 双体$\Lambda$N 参数和三体$\Lambda$NN 参数被发现对于束缚所研究的超核系统非常重要。随着早期工作中使用的 Lambda NN 相互作用参数值的减少，$_\Lambda^4$H 和$_\Lambda^4$H$^*$的结合能值存在显著差异。此外，$\Lambda$N 相互作用参数也被发现对束缚起重要作用。 显示英文摘要

摘要： Variational Monte Carlo study has been done for the two hypernuclear systems $_\Lambda^4$H and $_\Lambda^4$H$^*$ for calculation of binding energies. For the two hypernuclear systems under study, different potential models have been used for the interactions involved in these hypernuclear systems. ArgonneV$_{18}$ NN, Urbana IX NNN and phenomenological $\Lambda$N and $\Lambda$NN potentials have been used in our study. Our potential models are based on our previous studies on different double lambda hypernuclear systems. From our results, hyperon-nucleon parameters ie. two-body $\Lambda$N parameter and three-body $\Lambda$NN parameters are found to be important for binding the hypernuclear systems under study. With reduction in the values of Lambda NN interaction parameters used in earlier works , there is significant difference in the values of binding energy of $_\Lambda^4$H and $_\Lambda^4$H$^*$. Also, $\Lambda$N interaction parameters are also found to play important role in binding.
