Decuplet baryons in a hot medium

The thermal properties of the light decuplet baryons are investigated in the framework of the thermal QCD sum rules. In particular, the behavior of the mass and residue of the Δ , Σ ∗ , Ξ ∗ , and Ω baryons with respect to temperature are analyzed taking into account the additional operators appearin...

Zusammenfassung:	The thermal properties of the light decuplet baryons are investigated in the framework of the thermal QCD sum rules. In particular, the behavior of the mass and residue of the Δ , Σ ∗ , Ξ ∗ , and Ω baryons with respect to temperature are analyzed taking into account the additional operators appearing in the Wilson expansion at finite temperature. It is found that the mass and residue of these particles remain overall unaffected up to T ≃ 150 MeV but, beyond this point, they start to diminish considerably.
