1  Reconstructed in ${{\mathit \Xi}_{{{b}}}^{-}}$ $\rightarrow$ ${{\mathit \Xi}_{{{c}}}^{0}}{{\mathit \pi}^{-}}$, ${{\mathit \Xi}_{{{c}}}^{0}}$ $\rightarrow$ ${{\mathit p}}{{\mathit K}^{-}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$ decays. Used ${{\mathit \Lambda}_{{{b}}}^{0}}$ $\rightarrow$ ${{\mathit \Lambda}_{{{c}}}^{+}}{{\mathit \pi}^{-}}$ for normalization.
2  Supersedes AAIJ 2014BJ and AAIJ 2024AJ.
