      abstract     = {The $\Xi_c^0$ baryon is unstable and usually decays into
                      charmless final states by the $c→su{\overline{d}}$
                      transition. It can, however, also disintegrate into a
                      $π^−$ meson and a $Λ^+_c$ baryon via $s$ quark decay or
                      via $cs→dc$ weak scattering. The interplay between the
                      latter two processes governs the size of the branching
                      fraction $B(\Xi_c^0→π^−Λ^+_c)$, first measured here to
                      be (0.55±0.02±0.18)\%, where the first uncertainty is
                      statistical and second systematic. This result is compatible
                      with the larger of the theoretical predictions that connect
                      models of hyperon decays using partially conserved axial
                      currents and SU(3) symmetry with those involving the
                      heavy-quark expansion and heavy-quark symmetry. In addition,
                      the branching fraction of the normalization channel,
                      $B(\Xi_c^+→pK^−π^+)$=(1.135±0.002±0.387)\% is
                      measured.},
