标题： Analysis of the $\mathrm{X_{AV}}$ state through its electromagnetic properties

摘要： 为了更好地理解多夸克态背后的夸克-胶子动力学，我们系统地研究了它们的电磁性质。 在本研究中，考虑该态的夸克组成$[ud][\bar{c}\bar{s}]$的二夸克-反二夸克构型，在QCD轻子面上求和规则方法框架下，研究了理论上预测的具有量子数$\mathrm{J^P = 1^+}$的单重味 charm 状态的磁矩和四极矩。 磁矩和四极矩的预测结果分别为$\mu_{\mathrm{X_{AV}}}=-0.89 ^{+0.14}_{-0.12}~\mu_N $和$\mathcal{D}_{\mathrm{X_{AV}}} = (-0.46 ^{+0.07}_{-0.06})\times 10^{-2} ~\mbox{fm}^2$。 所得结果有助于确定该态的精确性质。 这项工作有望激发实验上对多夸克系统电磁性质研究的兴趣。 显示英文摘要

摘要： To improve our understanding of the quark-gluon dynamics underlying multiquark states, we systematically study their electromagnetic properties. In this study, the magnetic and quadrupole moments of the theoretically predicted singly-charmed state with the quantum numbers $\mathrm{J^P = 1^+}$ is investigated within the framework of the QCD light-cone sum rules method by considering the diquark-antidiquark configuration of this state with quark contents $[ud][\bar{c}\bar{s}]$. The predicted results for the magnetic and quadrupole moments are as $\mu_{\mathrm{X_{AV}}}=-0.89 ^{+0.14}_{-0.12}~\mu_N $ and $\mathcal{D}_{\mathrm{X_{AV}}} = (-0.46 ^{+0.07}_{-0.06})\times 10^{-2} ~\mbox{fm}^2$. The results obtained can be useful in determining the exact nature of this state. This work will hopefully stimulate experimental interest in the study of the electromagnetic properties of multiquark systems.
