The mass and decay constants of \(\rho _2,~\omega _2\) and a missing member in the \( 2^{--} \) nonet along with their first excited states are analyzed by the Thermal QCD sum rules approach, including QCD condensates up to dimension five. Mass and decay constant values of these mesons are stable from \(T=0\) up to \(T \cong 120 ~\mathrm {MeV}\). However, after this threshold point, our numerical analyses indicates that they begin to diminish with increasing temperature. When we compare the hadronic parameters with their vacuum values, masses of these mesons and their first excited states decrease between (1–13%) from the PDG data and (10–26%) for the decay constants. However they diminish in the interval of (9–26%) and (2–34%) respectively with regards to Regge Trajectory Model data. We expect our numerical results will be confirmed by future heavy-ion collision experiments.

通过热QCD和规则方法分析\（\ rho _2，〜\ omega _2 \）和\（2 ^ {-} \） nonet中缺少成员的质量常数和衰减常数以及它们的第一个激发态。 ，包括QCD冷凝物直至尺寸5。这些介子的质量和衰减常数值从\（T = 0 \）到\（T \ cong 120〜\ mathrm {MeV} \）都是稳定的。但是，在此阈值点之后，我们的数值分析表明，它们随着温度的升高而开始减小。当我们将强子参数与其真空值进行比较时，这些介子的质量及其第一激发态在PDG数据中的衰减范围为（1-13％），而在衰减常数之间的减小范围为（10-26％）。但是，就Regge弹道模型数据而言，它们分别在（9–26％）和（2–34％）的区间内减小。我们希望我们的数值结果将在未来的重离子碰撞实验中得到证实。
