Thermal behaviors of light unflavored tensor mesons in the framework of QCD sum rule

In this paper, we investigated the sensitivity of the masses and decay constants of f(2)(1270) and a(2)(1320) tensor mesons to the temperature using OCD sum rule approach. In our calculations, we take into account new additional operators appearing in operator product expansion (OPE). At the end of numerical analyses we show that at decon finement temperature the decay constants and masses decreased by 6% and 96% of their vacuum values, respectively. Our results on the masses and decay constants at zero temperature of the tensor mesons are consistent with the experimental data as well as the vacuum sum rules predictions.
