  "abstract": "<p>The doubly charged scalar resonance ${T}_{cs0}^{a}\\left(2900{\\right)}^{++}$ is studied in the context of the hadronic molecule model. We consider ${T}_{cs0}^{a}\\left(2900{\\right)}^{++}$ as a molecule $M={D}^{*+}{K}^{*+}$ composed of vector mesons and calculate its mass, current coupling, and full width. The spectroscopic parameters of $M$, i.e., its mass and current coupling, are found by means of the QCD two-point sum rule method by taking into account vacuum expectation values of quark, gluon, and mixed operators up to dimension 10. The width of the molecule $M$ is evaluated through the calculations of the partial widths of the decay channels $M\\to {D}_{s}^{+}{\\pi }^{+}$, $M\\to {D}_{s}^{*+}{\\rho }^{+}$, and $M\\to {D}^{*+}{K}^{*+}$. Partial widths of these processes are determined by strong couplings ${g}_{1}$, ${g}_{2}$, and ${g}_{3}$ of particles at vertices $M{D}_{s}^{+}{\\pi }^{+}$, $M{D}_{s}^{*+}{\\rho }^{+}$, and $M{D}^{*+}{K}^{*+}$, respectively. We calculate the couplings ${g}_{i}$ by employing the QCD light-cone sum rule approach and technical tools of the soft-meson approximation. Predictions obtained for the mass $m=\\left(2924\u00b1107\\right)\\text{}\\text{}\\mathrm{MeV}$ and width $\\Gamma =\\left(123\u00b125\\right)\\text{}\\text{}\\mathrm{MeV}$ of the hadronic molecule $M$ allow us to consider it as a possible candidate of the resonance ${T}_{cs0}^{a}\\left(2900{\\right)}^{++}$.</p>",
