  "abstract": "We study the inclusive lifetimes of $Ξ_{bc}^{+}$, $Ξ_{bc}^{0}$, and $Ω_{bc}^{0}$, with emphasis on the mixing between the spin-zero and spin-one $bc$-diquark configurations. The relevant hadronic matrix elements are evaluated in both the homogeneous bag model (HBM) and the nonrelativistic quark model (NRQM). At the benchmark mixing angles of $-23.0^\\circ$ for $Ξ_{bc}$ and $-23.5^\\circ$ for $Ω_{bc}$, the corresponding lifetime triplets are $\\left(τ_{Ξ_{bc}^{+}},τ_{Ξ_{bc}^{0}},τ_{Ω_{bc}^{0}}\\right)=\\left(0.421^{+0.093}_{-0.093},0.075^{+0.035}_{-0.010},0.223^{+0.074}_{-0.043}\\right)\\,\\mathrm{ps}$ in the HBM and $\\left(τ_{Ξ_{bc}^{+}},τ_{Ξ_{bc}^{0}},τ_{Ω_{bc}^{0}}\\right)=\\left(0.367^{+0.076}_{-0.070},0.100^{+0.032}_{-0.014},0.229^{+0.066}_{-0.042}\\right)\\,\\mathrm{ps}$ in the NRQM. Relative to the unmixed spin-one reference points, the $Ξ_{bc}^{0}$ and $Ω_{bc}^{0}$ lifetimes decrease by approximately $17\\%$-$19\\%$. Neither the minimum nor the maximum of the central lifetime curves occurs at a pure $S_{bc}=0$ or $S_{bc}=1$ configuration; the extrema instead lie at mixed angles with $\\left|ϕ_{\\mathcal{B}}\\right|\\simeq27^\\circ$-$63^\\circ$. The two pure-spin limits alone are therefore insufficient to characterize the full mixing-angle dependence.",
