We treat it as a state built of axial-vector diquark $b^{T}C\\gamma _{\\mu }c$ and antidiquark $\\overline{b}\\gamma _{\\nu }C \\overline{c}^{T}$, where $C$ is the charge conjugation matrix. The mass $m$ and current coupling $\\Lambda$ of this tetraquark are extracted from two-point sum rules. Our result for $m=(12.70 \\pm 0.09)~\\mathrm{GeV}$ proves that $T$ is unstable against strong dissociations to two-meson final states.
