Mass and full decay width of the hadronic tensor molecule M T=Bc∗ +Bc∗ - are examined in the framework of QCD sum rule method. To find the mass m and current coupling Λ of this state, we use the two-point sum rules. The result (12.87 ± 0.08)~ GeV for m indicates that MT can easily decay to pairs of J/ψΥ, ηbηc, Bc+Bc-, and Bc∗ +Bc∗ - mesons. Kinematically permitted ways for MT to transform to conventional mesons include also processes MT → D(∗)+D(∗ )-, D(∗ )0D(∗ )0, and Ds(∗)+Ds(∗)- triggered by annihilation of bb quarks in the molecule. The decays to meson pairs B(∗)+B(∗ )-, B(∗ )0B(∗ )0 , and Bs(∗)0Bs(∗ )0 generated by cc → light quarks are also among possible channels of the hadronic molecule MT. Technical tools of the three-point sum rule approach are applied to compute partial widths of these decays. Our results for the mass and width Γ_MT=(154 ± 19)~ MeV of the tensor molecule MT are important for experimental studies of fully heavy exotic structures.
