  "abstract": "The charmonium-like state $χ_{c1}(4010)$, recently observed by the LHCb Collaboration in $B^+ \\to D^{*\\pm}D^{\\mp}K^+$ decays, is investigated as an axial-vector $D^{*\\pm}D^{\\mp}$ molecular state within the QCD sum rule approach. A two-point sum rule incorporating quark, gluon, and mixed vacuum condensates up to dimension $10$ yields the mass and decay constant, $m_{χ_{c1}(4010)} = (4005.89 \\pm 47.15)~\\text{MeV}$ and $f_{χ_{c1}(4010)} = (2.87 \\pm 0.55)\\times 10^{-3}~\\text{GeV}^{4}$, in agreement with the LHCb measurement. Since this mass lies above the $D^{*\\pm}D^{\\mp}$ threshold, the strong coupling constants at the $χ_{c1}(4010)D^{*\\pm}D^{\\mp}$ vertices are extracted from three-point sum rules and used to compute the partial widths of the $D^{*-}D^{+}$ and $D^{*+}D^{-}$ channels. The resulting total width, $Γ_{χ_{c1}(4010)} = (57.64 \\pm 9.64)~\\text{MeV}$, is compatible with experiment within uncertainties. These results support a $D^{*\\pm}D^{\\mp}$ molecular interpretation of $χ_{c1}(4010)$ and offer sum-rule predictions for comparison with future measurements at BESIII, LHCb, and Belle~II.",
