论文摘要
我们计算了各向异性的质量和衰减常数 $π_2（1670）$，ISSCALAR $η_2（1645）$和$η_2（1870）$状态为$ 1^1d_2 $ case in Thermal QCD Sum规则框架中的基本状态nonet。该方法应用于高温，包括Quark，Gluon和混合冷凝水在内的高温媒介物的光谱变化，直至五个维度。我们发现它们的质量和衰减常数对低温区域的温度不敏感。在近乎危险的温度下，我们观察到质量呈$π_2$，$η_2（1645）$和$η_2（1870）$的指数下降，但是虽然$π_2$的衰减常数下降了，但$π_2$却下降，$π_2$下降，$π_2$降低了$η_2（1645）$和$ h最高$η_2（1870）$ As an a a a infood a foonformation afood。在$ t \ neq 0 $上修改冷凝物对于在热培养基中的更改所考虑的介子属性至关重要。我们讨论和解释结果的物理意义的含义。
We have computed the masses and decay constants of isotriplet $π_2(1670)$, the isoscalar $η_2(1645)$ and $η_2(1870)$ states as the ground-state nonet of $1^1D_2$ case within the Thermal QCD sum rules framework. This method is applied to the spectral changes of pseudotensor mesons at high temperatures including quark, gluon, and mixed condensates up to the five dimensions. We found that their masses and decay constants are insensitive to temperature in low-temperature regions. At the near-critical temperature, we observed an exponential decrease of the masses of $π_2$, $η_2(1645)$, and $η_2(1870)$, but while the decay constant of $π_2$ is fallen, that of $η_2(1645)$ and $η_2(1870)$ is increased as a function of temperature. The modification of condensates at $T\neq 0$ is crucial to the change of considered mesons properties in a hot medium. We discuss and interpret the implications of the physical meaning of our results.
