摘要：

We review the recent results from the Belle experiment on the measurements of branching fractions and decay asymmetry parameters (alpha) for the hadronic weak decays of charmed baryons, including Lambda(+)(c) -> B + P: Lambda(+)(c) ->(Lambda Sigma(0)) h+ (h= pi, K) and Lambda(+)(c) ->Sigma+(pi(0), eta, eta ' ); Xi(0)(c) -> B + V: Xi(0)(c)->Xi(-) pi(+); Xi(0)(c)-> B + V: Xi(0)(c) ->Lambda(K)(*0), Xi(0)(c) ->Sigma(0)(K)(*0), and Xi(0)(c) ->Sigma K-+(*-). In addition, we present an overview of the searches for CP violation via the alpha-induced CP asymmetry for Lambda(+)(c) ->(Lambda, Sigma(0))h(+) and Xi(0)(c)->Xi(-)pi(+). Finally, we discuss the promising decay modes of Omega(0)(c) which can be measured in the near future and are indispensable in searching for CP violation in the charm sector.
