摘要：

We study the non-leptonic two-body weak decays of Lambda(+)(c)(2286) -> BnM with B-n (M) representing as the baryon (meson) states. Based on the SU(3) flavor symmetry, we can describe most of the data reexamined by the BESIII Collaboration with higher precisions. However, our result of B(Lambda(+)(c) -> p pi(0)) = (5.6 +/- 1.5) x 10(-4) is larger than the current experimental limit of 3 x10(-4) (90% C.L.) by BESIII. In addition, we find that B(Lambda(+)(c) +Sigma+K-0) =(8.0 +/- 1.6) x10(-4), B(Lambda(+)(c) -> Sigma+ eta') =(1.0(-0.8)(+1.6)) x 10(-2), and B(Lambda(+)(c) -> p eta') =(12.2(-8.7)(+14.3)) x10-4, which are accessible to the BESIII experiments.
