Melting of 𝜌2 meson at extreme temperatures

Abstract

The thermal properties of the light tensor ρ2 meson with quantum numbers JPC = 2- are studied at finite temperature. In our calculations, two-point Thermal QCD sum rules approach is employed including contributions up to operator dimension-5 of quark, gluon, and quark-gluon mix condensates. We present thermal effects on the main hadronic properties namely, mass and decay constant of the considered resonance in SU(3) nonet, which provides more knowledge about axial-tensor family for experiments. The non-perturbative treatments of the light quark dynamics results in mass spectra at zero temperature agree with available experimental data and thermal behavior of meson parameters can be tested in future experiments.
