Mixing-angle sensitivity of inclusive $Ξ_{bc} $ and $Ω_{bc}$ lifetimes

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 mode
