光锥QCD中$Z_b(10610)$的磁偶极矩

Magnetic dipole moment of $Z_b(10610)$ in light-cone QCD

U. Ozdem, K. Azizi

摘要:

利用双夸克-反双夸克流和分子内插流,利用光锥QCD求和规则计算了奇异$Z_b(10610)$态的磁偶极矩。磁偶极矩在双夸克-反双夸克图象中表示为$μ_{Z_b}=1.73\pm 0.63~μ_N$,在分子图象中表示为$μ_{Z_b}=1.59\pm 0.58~μ_N$。在这两个图片中所获得的结果与其他理论研究的结果的光谱参数的$Z_b(10610)$状态可能是有用的,在确定的性质和夸克组织的这种状态。

英文摘要:

The magnetic dipole moment of the exotic $Z_b(10610)$ state is calculated within the light cone QCD sum rule method using the diquark-antidiquark and molecule interpolating currents. The magnetic dipole moment is obtained as $μ_{Z_b}=1.73\pm 0.63~μ_N$ in diquark-antidiquark picture and $μ_{Z_b}=1.59\pm 0.58~μ_N$ in the molecular case. The obtained results in both pictures together with the results of other theoretical studies on the spectroscopic parameters of the $Z_b(10610)$ state may be useful in determination of the nature and quark organization of this state.
