论文摘要
轴向调度介孔NONETS的质量和衰减常数$ρ_2，〜Ω_2 $和缺失的成员以及其第一个激发态的质量和衰减常数，以及他们的第一个激发态，通过热QCD总规则模型（包括QCD凝结至尺寸为fiven）的热量QCD总规则模型。从$ t = 0 $到〜$ t \ cong 120〜 \ mathrm {mev} $，质量和衰减的常数值在温度的变化方面非常稳定。然而，几乎在这些阈值之后，我们的数值分析表明它们随着温度的升高而开始减少。与真空值相比，这些媒介的质量价值及其第一个激发状态的质量值降低了约$（1-13 \％）$，根据PDG数据的衰减常数$（10-26 \％）$，分别根据PDG数据和$（9-26 \％）$和$（2-34 \％）$（2-34 \％\％）$在相应的regge graightory thermand of Sum QCD Sum QCD QCD QCD中的regge graightory模型中分别计算。实验结果已经很丰富，但预计将在持续和未来的重型离子实验计划中成长，从而使我们能够比较结果。
The mass and decay constant of the axial-tensor meson nonets $ρ_2,~ω_2$ and a missing member and also their first excited states are analyzed by the Thermal QCD sum rules model including QCD condensates up to dimension five. Mass and decay constant values in terms of variations of temperature are very well stable from $T=0$ up to ~$T \cong 120 ~\mathrm{MeV}$. However nearly after these threshold, our numerical analysis indicate that they begin to diminish with increasing temperature. Mass value of these mesons and their first excited states decrease about $(1-13\%)$ compared to vacuum values and $(10-26\%)$ for the decay constants according to PDG data and $(9-26\%)$ and $(2-34\%)$ respectively concerning Regge Trajectory Model in the corresponding Thermal QCD sum rules calculations. The experimental results are already copious, but expected to grow up at ongoing and future heavy-ion experimental programs allowing us to compare our results.
