Test Flavor SU(3) symmetry in Exclusive Λ_c decays
read the original abstract
Flavor SU(3) symmetry is a powerful tool to analyze charmed baryon decays, however its applicability remains to be experimentally validated. Since there is not much data on $\Xi_c$ decays, various exclusive $\Lambda_c$ decays especially the ones into a neutron state are essential for the test of flavor symmetry. These decay modes are also helpful to investigate final state interactions in charmed baryon decays. In this work, we discuss the explicit roles of $\Lambda_c$ decays into a neutron in testing the flavor symmetry and exploring final state interactions. The involved decay modes include semileptonic decays, two-body and three-body non-leptonic decays, but all of them have not been experimentally observed to date.

Probing the isospin structure and low-lying resonances in $\Lambda_c^+ \to n\bar{K}^0 \pi^+$ decays
The chiral unitary calculation predicts a narrow peak from N(1535) in the pi+ n invariant mass spectrum and a dip from Lambda(1670) in the K0bar n spectrum, supporting the molecular interpretation of these resonances.
