是否为$N\barΩ$绑定状态？
Are $N\barΩ$ bound states?
摘要：
受STAR合作组对$NΩ$重子的实验研究进展的启发，我们在夸克离域色屏蔽模型的框架下研究了$N\barΩ$系统。结果表明，$N$和$\barΩ$之间的吸引力比$N$和$Ω$之间的吸引力稍大，说明$N\barΩ$比$NΩ$更有可能形成束缚态.动力学计算表明，$J^{P}=1^{+}$和$2^{+}$ $N\barΩ$系统都是束缚态。这两个态的结合能比含$J^{P}=2^{+}$的$NΩ$体系的结合能大，含$J^{P}=1^{+}$的$NΩ$体系是未结合的.低能散射相移、散射长度和有效射程的计算也支持了$J^{P}=1^{+}$和$2^{+}$的$N\barΩ$束缚态的存在。因此，$N\barΩ$态是较好的六夸克态，在实验中可望得到较强的信号.
英文摘要：
Inspired by the progress of the experimental search of the $NΩ$ dibaryon by the STAR collaboration, we study $N\barΩ$ systems in the framework of quark delocalization color screening model. Our results show that the attraction between $N$ and $\barΩ$ is a little bit larger than that between $N$ and $Ω$, which indicates that it is more possible for the $N\barΩ$ than the $NΩ$ system to form bound states. The dynamic calculations state that both the $J^{P}=1^{+}$ and $2^{+}$ $N\barΩ$ systems are bound states. The binding energy of these two states are deeper than that of $NΩ$ systems with $J^{P}=2^{+}$, and the $NΩ$ system with $J^{P}=1^{+}$ is unbound. The calculation of the low-energy scattering phase shifts, scattering length and the effective range also supports the existence of the $N\barΩ$ bound states with $J^{P}=1^{+}$ and $2^{+}$. So the $N\barΩ$ states are better hexaquark states and stronger signals are expected in experiments.
