分子五夸克态$Ξ_b(6227)$的磁矩

Magnetic moment of the $Ξ_b(6227)$ as a molecular pentaquark state

U. Ozdem

摘要:

考虑到$Ξ_b (6227)$态处于分子结构中,本文采用光锥QCD求和规则提取了该态的磁矩。得到的数值结果为$μ_{Ξ_b}= 0.12 \pm 0.03~μ_N$。这种状态的磁矩包含了其内部结构和形状变形的重要信息。在未来的实验装置中测量$Ξ_b(6227)$态的磁矩,将有助于确定该态的量子数,以及理解该态的内部结构。

英文摘要:

In this study, considering that the $Ξ_b (6227)$ state is in molecular structure, the magnetic moment of this state is extracted in the light-cone QCD sum rules. The numerical result is obtained as $μ_{Ξ_b}= 0.12 \pm 0.03~μ_N$. The magnetic moment of this state contains important information of its internal structure and shape deformations. Measurement of the magnetic moment of the $Ξ_b(6227)$ state in future experimental facilities can be very helpful in identification of the quantum numbers, as well as comprehension of the inner structure of this state.
