通过QCD求和规则确定$J^P = 3^-$介子的多极矩

Determination of the multipole moments of the $J^P = 3^-$ mesons via QCD sum rules

T. M. Aliev, S. Bilmis, M. Savci

AI总结:

该研究利用光锥求和规则确定了$J^P = 3^-$张量介子的多极矩,与SU(3)味对称框架下光锥螺旋度形式论的预测一致,为理解这些介子的性质及衰变道提供了深入见解。

摘要:

利用光锥求和规则得到了$J^P = 3^-$张量介子的多极矩。我们将结果与SU(3)味对称框架下光锥螺旋度形式论的预测进行了比较,观察到两种方法间存在良好的一致性。所获张量介子多极矩为深入了解其性质及更好理解这些介子的强衰变和电磁衰变道提供了更深刻的见解。

英文摘要:

The multipole moments of the $J^P = 3^-$ tensor mesons are obtained using light-cone sum rules. Our results are compared with the predictions of the light-cone helicity formalism within the framework of SU(3) flavor symmetry. We observe a good agreement between the two approaches. The obtained multipole moments of tensor mesons provide deeper insights into their properties and better understanding of the strong and electromagnetic decay channels of these mesons.
