$NDK$、$\bar{K} DN$和$ND\bar{D}$分子

$NDK$, $\bar{K} DN$ and $ND\bar{D}$ molecules

C. W. Xiao, M. Bayar, E. Oset

摘要:

我们从理论上研究了由三个强子组成的重子系统,其中包含一个核子和一个D介子,以及另一个介子,$\bar{D}, K$或$\bar{K}$。该系统的研究使用固定中心近似的Faddeev方程。该研究假设$K$或$\bar{K}$在$DN$团簇上的散射,这是已知的产生$Λ_c(2595)$,或核子在$D\bar{D}$团簇上的散射,这已被证明产生一个隐藏的魅力共振X(3700)。我们还调查的配置的$N$上的$KD$集群,这是已知的生成的$D_{s0}^*(2317)$的散射。在所有情况下,我们发现绑定状态,与$NDK$系统,异国情调的性质,更多的约束比$\bar{K} DN$。

英文摘要:

We investigate theoretically baryon systems made of three hadrons which contain one nucleon and one D meson, and in addition another meson, $\bar{D}, K$ or $\bar{K}$. The systems are studied using the Fixed Center Approximation to the Faddeev equations. The study is made assuming scattering of a $K$ or a $\bar{K}$ on a $DN$ cluster, which is known to generate the $Λ_c(2595)$, or the scattering of a nucleon on the $D\bar{D}$ cluster, which has been shown to generate a hidden charm resonance named X(3700). We also investigate the configuration of scattering of $N$ on the $KD$ cluster, which is known to generate the $D_{s0}^*(2317)$. In all cases we find bound states, with the $NDK$ system, of exotic nature, more bound than the $\bar{K} DN$.
