Hidden-Beauty Broad Resonance Yb(10890) in Thermal QCD
In this work, the mass and pole residue of resonance Yb is studied by using QCD sum rules approach at finite temperature. Resonance Yb is described by a diquark-antidiquark tetraquark current, and contributions to operator product expansion are calculated by including QCD condensates up to dimension...

In this work, the mass and pole residue of resonance Yb is studied by using QCD sum rules approach at finite temperature. Resonance Yb is described by a diquark-antidiquark tetraquark current, and contributions to operator product expansion are calculated by including QCD condensates up to dimension six. Temperature dependencies of the mass mYb and the pole residue λYb are investigated. It is seen that near a critical temperature (Tc≃190 MeV), the values of mYb and λYb decrease to 87% and to 44% of their values at vacuum. |
