We present the first measurements of absolute branching fractions of ${\mathrm{\ensuremath{\Xi}}}_{c}^{0}$ decays into ${\mathrm{\ensuremath{\Xi}}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$, $\mathrm{\ensuremath{\Lambda}}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$, and $p{K}^{\ensuremath{-}}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$ final states. The measurements are made using a dataset comprising $(772\ifmmode\pm\else\textpm\fi{}11)\ifmmode\times\else\texttimes\fi{}{10}^{6}$ $B\overline{B}$ pairs collected at the $\mathrm{\ensuremath{\Upsilon}}(4S)$ resonance with the Belle detector at the KEKB ${e}^{+}{e}^{\ensuremath{-}}$ collider. We first measure the absolute branching …
