论文摘要
仍不存在应在PDG的进一步状态下发生的轴向张量家族的等构构件。在这项研究中，对该组中量子数是否未知的X状态之一进行了分析，是分配下缺失共振的候选者$ 2^3D_2 $。此外，用热平均值替换时间演化运算符，我们构建了满足热QCD总规则方法的修改后的相关器。我们确定所考虑的非ET成员的耐药参数对温度的增加敏感。这些知识有助于完成$ J^{pc} = 2^{ - } $ light meson nonet，并且还探索即将进行的重型离子碰撞实验中的热媒介行为。
The isoscalar member of the axial-tensor family that should take place in the further states of the PDG is still absent. In this study, analyzes are made as to whether one of the X states whose quantum numbers are unknown in this group, is a candidate for the missing resonance under the assignment $ 2^3D_2 $. Moreover, replacing the time evolution operator with the thermal average one, we construct the modified correlator satisfying Thermal QCD sum rules approach. We determine that the hadronic parameters of the considered nonet member are sensitive to the increment of temperature. This knowledge can be helpful to complete the $J^{PC} = 2^{--}$ light meson nonet and also explore the hot medium behaviors at upcoming heavy-ion collision experiments.
