论文摘要
由LHCB合作的最新发现的最新发现的Tetraquark $ T^+_ {Cc} $，我们研究了可能达到双重浓度的Pentaquark Statum $ J^p = 1/2^ - $ j^p = 1/2^ - 和$ J^p = 3/2^ - $内的磁性时刻。在分析中，这些可能的五夸克状态在diquark-diquark-antiquark结构中被考虑。 HADRON的磁矩编码有关HADRON内部电荷和磁化分布的有用细节，这有助于我们找出它们的几何配置。作为乘积，还提取了自旋3/2倍增五夸克状态的电二极管和磁性八极矩。这些值显示非球形电荷分布。以不同的理论方法检查这些可能的双重五夸克状态的磁性矩，这将是有趣且有用的。
Motivated by the latest discovery of doubly-charmed tetraquark $T^+_{cc}$ by LHCb collaboration, we have studied the magnetic moments of the possible doubly-heavy pentaquark states with quantum numbers $J^P = 1/2^-$ and $J^P = 3/2^-$ within the light-cone sum rules method. In the analysis, these possible pentaquark states are considered in diquark-diquark-antiquark structure. The magnetic moments of hadrons encode helpful details about the distributions of the charge and magnetization inside the hadrons, which help us to figure out their geometric configurations. As a by product, the electric quadrupole and magnetic octupole moments of the spin-3/2 doubly-heavy pentaquark states are also extracted. These values show a non-spherical charge distribution. It will be interesting and useful to examine the magnetic moments of these possible doubly-heavy pentaquark states with different theoretical approaches.
