A Diagrammatic Analysis of Two-Body Charmed Baryon Decays with Flavor Symmetry.

We study the two-body anti-triplet charmed baryon decays based on the diagrammatic approach with SU(3) flavor symmetry. We extract the two W -exchange effects as E_B and E' that contribute to the Λ c + → Ξ 0 K + decay, together with the relative phases, where E_B gives the main contribution. Besides, we find that B Λ c + → p π 0 = 0.8 − 0.8 + 0.9 × 10 − 4 ,which is within the experimental upper bound. Particularly, we obtain B Ξ c + → Ξ 0 π + = 9.3 ± 3.6 × 10 − 3 , B Ξ c 0 → Ξ − π + Λ 0 K ¯ 0 = 19.3 ± 2.8 8.3 ± 5.0 × 10 − 2 and B Ξ c 0 → Ξ − K + = 5.6 ± 0.8 × 10 − 4 , which all agree with the data. For the singly Cabibbo suppressed Λ c + decays, we predict that B Λ c + → n π + pη ' Σ + K 0 = 7.7 ± 2.0 7.1 ± 1.4 19.1 ± 4.8 × 10 − 4 , which are accessible to the experiments at BESIII, BELLEII and LHCb.
