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 \(\textrm{J}^\textrm{P} = 1^{+}\) 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 \(\mathcal {D}_{\mathrm {X_{AV}}} = (-0.46 ^{+0.07}_{-0.06})\times 10^{-2} ~\text{ fm}^2\). 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.

为了提高我们对多夸克态背后的夸克-胶子动力学的理解，我们系统地研究了它们的电磁特性。在本研究中，在 QCD 框架内研究了理论上预测的具有量子数\(\textrm{J}^\textrm{P} = 1^{+}\)的单魅力态的磁矩和四极矩光锥和规则方法，通过考虑具有夸克含量的该状态的双夸克-反双夸克配置\([ud][\bar{c}\bar{s}]\)。磁矩和四极矩的预测结果为\(\mu _{\mathrm {X_{AV}}}=-0.89 ^{+0.14}_{-0.12}~\mu _N \)和\(\mathcal {D}_{\mathrm {X_{AV}}} = (-0.46 ^{+0.07}_{-0.06})\times 10^{-2} ~\text{fm}^2\)。获得的结果可用于确定该状态的确切性质。这项工作有望激发人们对多夸克系统电磁特性研究的实验兴趣。
