Abstract
In this paper, we investigated the sensitivity of the masses and decay constants of f2(1270) and a2(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 deconfinement 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.
Highlights
Recent years, in order to understand properties of matter at high energies heavy-ion collision experiments are performed [1,2,3,4,5,6]
According to thermal QCD, around critical temperature, Tc = 175M eV, a transition occurs from hadronic matter to quark-gluon plasma (QGP) phase which probably exists in early universe and neutron stars
To extend the QCD sum rule method to finite temperatures, we assume that the Wilson expansion and the quark-hadron duality approximation are valid, but the quark and gluon condensates are changed with thermal expectation expressions [13]
