We study the decays of the antitriplet charmed baryon state (Ξc0,Ξc+,Λc+) based on the SU(3) flavor symmetry. In particular, after predicting B(Ξc0→Ξ−π+)=(15.7±0.7)×10−3 and B(Ξc+→Ξ−π+π+)=(14.7±8.4)×10−3, we extract that B(Ξc0→ΛK−π+,ΛK+K−,Ξ−e+νe)=(16.8±2.3,0.45±0.11,48.7±17.4)×10−3 and B(Ξc+→pKs0Ks0,Σ+K−π+,Ξ0π+π0,Ξ0e+νe)=(1.3±0.8,13.8±8.0,33.8±21.9,33.8−22.6+21.9)×10−3. We also find that B(Ξc0→Ξ0η,Ξ0η′)=(1.7−1.7+1.0,8.6−6.3+11.0)×10−3, B(Ξc0→Λ0η,Λ0η′)=(1.6−0.8+1.2,9.4−6.8+11.6)×10−4 and B(Ξc+→Σ+η,Σ+η′)=(28.4−6.9+8.2,13.2−11.9+24.0)×10−4. These Ξc decays with the branching ratios of O(10−4–10−3) are clearly promising to be observed by the BESIII and LHCb experiments.
