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 Yb are investigated. It is seen that near a critical temperature (Tc similar or equal to 190MeV), the values of mYb and Yb decrease to 87% and to 44% of their values at vacuum.engopenAccessarticle201900047365570000110.1155/2019/80918652-s2.0-85068617756
