“…In this manner there are many studies about the effect of temperature on the fundamental parameters of hadrons in the literature [3,4,18,19]. Due to the temperature dependence of the color screening radius in the QGP, it is expected that mesons with different flavors melt at certain temperatures.…”

The mass and decay constants of $$\rho _2,~\omega _2$$ ρ 2 , ω 2 and a missing member in the $$ 2^{--} $$ 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 $$T=0$$ T = 0 up to $$T \cong 120 ~\mathrm {MeV}$$ T ≅ 120 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.

The mass and decay constant of the axial-tensor meson nonets ρ2, ω2 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 ∼ = 120 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.
