Motivated by the very recent discovery of the strange hidden-charm exotic state Zcs(3985) by the BESIII Collaboration, we study possible interpretation of this exotic state both at T = 0 and T = 0. We analytically compute the mass and meson-current coupling constant of this resonance with spinparity J P C = 1 +− at finite temperature approximation up to sixth order of the thermal operator dimension including non-perturbative contributions. Extracting thermal mass and meson-current coupling constant sum rules, the modifications on properties of Zcs(3985) state in hot medium is determined. As a by product, the hadronic parameters of the bottom partner of Zcs( 3985) is estimated as well. Moreover the search of temperature effects on the hadronic parameters of hidden-charm meson Zcs(3985) and the bottom partner make us understand the phase transitions, chiral symmetry breaking and the properties of hot-dense matter in QCD.

“…[10] the leptonic decay constant of both pseudoscalar and vector mesons decreases with increasing T and vanishes at a critical temperature T c . Conversely, the masses show little dependence on the temperature, except very close to T c , where the pseudoscalar meson masses rise slightly by (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)%, and the vector meson masses diminish by some (20-30)%. In other works, the D s0 (2317) meson mass decreases with increasing temperature and loses approximately (10-15)% of its mass and also the decay constant decreases with growing temperature and vanishes approximately when the critical temperature is assumed to be 150 MeV in ref.…”

In this work the properties of the axial-tensor K2(1820) meson in a hot medium are investigated. The mass and the decay constant of this state are calculated via thermal QCD sum rules considering QCD condensates up to dimension five. Our analysis show that both mass and decay constant stay almost monotonous up to certain temperatures and then they diminish with increasing temperature. The mass and decay constant estimated at zero temperature are in good agreement with the present experimental data and theoretical estimations.

The thermal behavior of the spectroscopic parameters of the S-wave single heavy baryons * Q , * Q and * Q with spin-3/2 are investigated in QCD at finite temperature. We analyze the variations of the mass and residue of these baryons taking into consideration the contributions of QCD thermal condensates up to dimension eight in Wilson expansion. At finite temperature, due to the breakdown of the Lorentz invariance by the choice of reference frame and presence of an extra O(3) symmetry, some new four-dimensional operators come out in the form of the fermionic and gluonic parts of the energy momentum tensor that are taken into account in the calculations. Our analyses show that at lower temperatures, the parameters of baryons under consideration are not affected by the medium. These parameters, however, show rapid variations with respect to temperature at higher temperatures near to a pseudo-critical temperature, after which the baryons are melted. The results of the masses and residues at T → 0 limit are compatible with the available experimental data and predictions of other theoretical studies.
