  "abstract": "In 2021, the LHCb Collaboration observed the $B_{sJ}(6114)$ state in the $B^\\pm K^\\mp$ invariant mass spectrum. It is currently the highest-mass bottom-strange state listed by the Particle Data Group (PDG). However, its spin-parity quantum numbers have not yet been experimentally determined, and its internal structure remains under debate. Although several quark-model interpretations have been proposed, including the $1^3D_1$ state and a member of the $1D(2^-,3^-)$ doublet, the possibility of a hadronic molecular structure for this state has not yet been systematically investigated. We investigate the possibility of interpreting \\(B_{sJ}(6114)\\) as a \\(B^{(*)}\\bar{K}^{*}\\) molecular state within the one-boson-exchange model. By solving the Schrödinger equation using the Gaussian expansion method, we study the bound-state properties with different spin-parity assignments, taking into account partial-wave mixing and coupled-channel effects. We further calculate the strong decay widths into the allowed \\(B^{(*)}\\bar{K}\\) channels and compare them with the experimental data. Our results show that the mass spectrum alone cannot uniquely determine the spin-parity of \\(B_{sJ}(6114)\\). However, the decay-width analysis disfavors the \\(J^P=0^+\\), \\(0^-\\), \\(1^+\\), \\(2^+\\), and \\(3^-\\) assignments, while the \\(J^P=1^-\\), \\(2^-\\), and \\(3^+\\) configurations remain compatible with the experimental constraints. Among these possibilities, the \\(J^P=1^-\\) assignment provides the best agreement with the measured decay width. These findings suggest that \\(B_{sJ}(6114)\\) may be a higher-partial-wave \\(B^{(*)}\\bar{K}^{*}\\) molecular state.",
