论文摘要
Motivated by the discovery of fully open-flavor tetraquark states $X_0(2900)$ and $X_1(2900)$ by the LHCb Collaboration, the magnetic dipole moment of the $X_1(2900)$ state with the quantum numbers $ J^{P} = 1^{-}$ is determined in the diquark-antidiquark picture using the light-cone sum rules.数值结果作为$μ_{x_1} = 0.79^{+0.36} _ { - 0.39} \，μ_n$。 Hadron的磁矩包含有关电荷分布和内部磁化的有用知识，这些知识可用于更好地了解其几何形状和夸克 - 胶状组织。 $ x_0（2900）$和$ x_1（2900）$的观察，作为前两个完全开放的多种多样的多Quark States，已经打开了一个新的窗口，以调查外来状态。在本研究中获得的结果可能会阐明对完全开放培训多Quark状态的特性的未来实验和理论搜索。
Motivated by the discovery of fully open-flavor tetraquark states $X_0(2900)$ and $X_1(2900)$ by the LHCb Collaboration, the magnetic dipole moment of the $X_1(2900)$ state with the quantum numbers $ J^{P} = 1^{-}$ is determined in the diquark-antidiquark picture using the light-cone sum rules. The numerical result is obtained as $ μ_{X_1}=0.79^{+0.36}_{-0.39}\,μ_N$. The magnetic moments of hadrons encompasses useful knowledge on the distributions of charge and magnetization their inside, which can be used to better understand their geometrical shapes and quark-gluon organizations. The observation of the $X_0(2900)$ and $X_1(2900)$ as the first two fully open-flavor multiquark states has opened a new window for investigation of the exotic states. The obtained results in the present study may shed light on the future experimental and theoretical searches on the properties of fully open-flavor multiquark states.
