论文摘要
通过$ξnα$的能级和$ξnα$系统的能量水平，$α$是吸引$ξn$ pap的$ξnα$系统的一种新方法来研究$ξn$相互作用的自旋依赖性依赖性，而无需更改其旋转旋转结构。 By using the Gaussian expansion method (GEM) with the state-of-the-art $ΞN$ potential obtained from lattice QCD calculations, it is found that $ΞNαα$ has spin-doublet bound states with $J^π={1^-}$ and $2^-$ in both isospin triplet and singlet channels. $ 1^ - $ - $ 2^ - $ 2^ - $ spin-doublet在ISO-Triplet和Iso-Singlet之间被发现与$^{\ rm S} {\ rm S}} {\ rm S} _0，^13} {13} {13} {\ rm s} { s} _0 $和$^{33} {\ rm s} _1 $ channels。提出了$（k^ - ，k^+）$和$（k^ - ，k^0）$ reactions $^{10} $ b目标的$ reactions以产生这些约束状态。
A new way to study the spin-isospin dependence of the $ΞN$ interaction is explored through the energy levels of $ΞNα$ and $ΞNαα$ systems with $α$ being a spectator to attract the $ ΞN$ pair without changing its spin-isospin structure. By using the Gaussian expansion method (GEM) with the state-of-the-art $ΞN$ potential obtained from lattice QCD calculations, it is found that $ΞNαα$ has spin-doublet bound states with $J^π={1^-}$ and $2^-$ in both isospin triplet and singlet channels. The inversion of the $1^-$-$2^-$ spin-doublet between the iso-triplet and the iso-singlet is found to be strongly correlated with the relative strengths of the $ΞN$ interaction in the $^{11}{\rm S}_0, ^{13}{\rm S}_1,^{31}{\rm S}_0$ and $^{33}{\rm S}_1$ channels. The $(K^-, K^+)$ and $(K^-,K^0)$ reactions on the $^{10}$B target are proposed to produce those bound states.
