They are modeled as four-quark mesons $T_{\\mathrm{1}}$ and $T_{\\mathrm{2}}$ composed of $b^{T}C\\sigma _{\\mu \\nu }\\gamma _{5}b$, $\\overline{c}\\gamma ^{\\nu }C \\overline{c}^{T}$ and $b^{T}C\\gamma _{\\mu }\\gamma _{5}b$, $\\overline{c}C \\overline{c}^{T}$ diquarks, respectively. The spectroscopic parameters of the tetraquarks $T_{\\mathrm{1}}$ and $T_{\\mathrm{2}}$ are determined in the context of the QCD two-point sum rule method.
