- Abstract
We review the recent results from the Belle experiment on the measurements of branching fractions and decay asymmetry parameters (α) for the hadronic weak decays of charmed baryons, including Λ c + → B + P : Λ c + → (Λ , Σ 0) h + ( h = π , K ) and Λ c + → Σ + (π 0 , η , η ′) ; Ξ c 0 → B + P : Ξ c 0 → Ξ − π + ; Ξ c 0 → B + V : Ξ c 0 → Λ K ¯ * 0 , Ξ c 0 → Σ 0 K ¯ * 0 , and Ξ c 0 → Σ + K * − . In addition, we present an overview of the searches for C P violation via the α -induced C P asymmetry for Λ c + → (Λ , Σ 0) h + and Ξ c 0 → Ξ − π + . Finally, we discuss the promising decay modes of Ω c 0 which can be measured in the near future and are indispensable in searching for C P violation in the charm sector.
