 First branching fraction measurement of the suppressed decay $\Xi_c^0\to \pi^-\Lambda_c^+$ / LHCb Collaboration The $\Xi_c^0$ baryon is unstable and usually decays into charmless final states by the $c \to s u\overline{d}$ transition. It can, however, also disintegrate into a $\pi^-$ meson and a $\Lambda_c^+$ baryon via $s$ quark decay or via $cs\to d c$ weak scattering.
