Properties of doubly charged scalar tetraquarks bbcc are investigated in the framework of the QCD sum rule method. We model them as diquark-antidiquark states X1 and X2 built of axial-vector and pseudoscalar diquarks, respectively. The masses and current couplings of these particles are computed using the QCD two-point sum rule method. Results m1=(12715 ± 80)~MeV and m2=(13370 ± 95)~MeV obtained for the masses of these particles are used to determine their kinematically allowed decay modes. The full width Γ 1 of the state X1 is evaluated by taking into account its strong decays to mesons 2Bc-, and 2Bc∗ -. The processes X2 → 2Bc-, 2Bc∗ - and Bc-Bc-(2S) are employed to estimate Γ2. Predictions obtained for the full widths Γ1=(63 ± 12)~ MeV and Γ2=(79 ± 14)~MeV of these structures and their masses may be utilized in experimental studies of fully heavy resonances.
