We model $T_{\\mathrm{ \\ \\ PS}} $ and $T_{\\mathrm{V}}$ as structures built of diquarks $ b^{T}C\\gamma_{5}b$, $\\overline{c}C\\overline{c}^{T}$ and $b^{T}C\\gamma _{5}b$ , $\\overline{c}C\\gamma_{\\mu}\\gamma_{5}\\overline{c}^{T}$, respectively, with $ C$ being the charge conjugation matrix. The spectroscopic parameters of the tetraquarks $T_{\\mathrm{PS}}$ and $T_{\\mathrm{V}}$, i.e., their masses and current couplings are calculated using QCD two-point sum rule method.
