标题： Examination of the lattice QCD-motivated strong attractive $ΩN$ potentials in the $Ω^- n p$ system

摘要： 在构型空间的Faddeev方程框架内，我们研究了$\Omega^{-} np$系统，采用强吸引晶格HAL QCD和Yukawa型介子交换势来描述$\Omega N$相互作用。 我们的形式主义包含了质子与$\Omega^{-}$之间的吸引库仑力，将系统视为三个非相同粒子对（$ABC$模型）。 在本研究中，我们评估了库仑相互作用对系统的影响，并将我们的结果与最近使用各种方法获得的$\Omega NN$（$AAC$模型）计算结果进行了比较。 $ABC$模型为\(\Omega NN\)系统提供了低能特性，这些特性与之前的计算有所不同。库仑势对$AAC$系统有微小的摄动效应，将三体束缚能移动了两体$BC$子系统的库仑能量，但仅轻微偏离等边三角形对称的空间构型。这些效应主要由强\(\Omega N\)相互作用驱动。我们证明了$\Omega^{-} np$系统的大结合能来自于$\Omega N$势的短程行为。 显示英文摘要

摘要： Within the framework of the Faddeev equations in configuration space, we examine the $\Omega^{-} np$ system, employing strongly attractive lattice HAL QCD and Yukawa-type meson exchange potentials for the $\Omega N$ interaction. Our formalism incorporates the attractive Coulomb force between the $\Omega^{-}$ and proton, treating the system as three non-identical particle pairs (the $ABC$ model). In this study, we assess the impact of the Coulomb interaction on the system and compare our results with recent $\Omega NN$ ($AAC$ model) calculations obtained using various approaches. The $ABC$ model yields low-energy characteristics for the \(\Omega NN\) system that differ from previous calculations. The Coulomb potential has a marginal perturbative effect on the $AAC$ system, shifting the three-body binding energy by the Coulomb energy of the two-body $BC$ subsystem, but only slightly deviating the spatial configuration from isosceles triangle symmetry. These effects are primarily driven by the strong \(\Omega N\) interaction. We demonstrate that the large binding energy of the $\Omega^{-} np$ system arises from the short-range behavior of the $\Omega N$ potentials.
