论文摘要
我们系统地研究多Quark状态的电磁特性。在这项研究中，受到最近一系列研究的启发，该研究表明可能存在$ d \ bar d^* k $州，我们检查了$ d \ bar d \ bar d^* k $ hexaquark State的磁矩，在三烯烃分子结构中，以及isospin和spin-parity量子和旋转量子量子$ i（j^p）= 3/2（j^p）= 3/2（1^ - 1^ - 1^ - 1^ - ）$ SUL。 $ d \ bar d^* k $分子六夸克状态获得的磁矩非常大，并且其幅度表明在将来的实验中可以访问它。作为副产品，还提取了$ d \ bar d^* k $分子六夸克状态的四极力矩。该值表示非球形电荷分布。 Hadron的磁矩包含有关其内部电荷和磁化的分布的宝贵知识，可以用来更好地了解其几何形状和夸克 - 格鲁恩组织。这项研究中给出的结果构成了该$ d \ bar d^* k $状态的磁矩的估计，应作为对该状态进行实验检查的灵感。
We systematically study the electromagnetic properties of multiquark states. In this study, inspired by the recent series of studies that showed the likely existence of a $ D \bar D^* K$ state, we examine the magnetic moment of $ D \bar D^* K$ hexaquark state in three-meson molecular structure, as well as having isospin and spin-parity quantum numbers $I(J^P) =3/2(1^-)$ via light-cone sum rules. The magnetic moment obtained for the $ D \bar D^* K$ molecular hexaquark state is quite large due to the double electric charge, and its magnitude indicates that it is accessible in future experiments. As a byproduct, the quadrupole moment of the $ D \bar D^* K$ molecular hexaquark state is also extracted. This value indicates a non-spherical charge distribution. The magnetic moments of hadrons contains valuable knowledge on the distributions of charge and magnetization their inside, which can be used to better understand their geometric shape and quark-gluon organizations. The results given in this study constitute an estimate of the magnetic moment of this $D \bar D^* K$ state and should serve as an inspiration to conduct experimental examinations of this state.
