Description
In this talk, we would like to report our recent theoretical studies on the $\Lambda_c^+$ hadronic decays, i.e., $\Lambda_c^+ \to \pi^+ K^- p$ (charged) and $\Lambda_c^+ \to \pi^+ \bar{K}^0 n$ (neutral), using the effective Lagrangian approach. Considering the strong $ud$-diquark correlation inside the $\Lambda_c^+$ baryon, we confine our model to that with the I=0 hyperon resonances and other meosonic contributions. The Belle experiment data are reproduced qualitatively well for the charged channel, and we provide theoretical predictions for the neutral channel as well. It tuns out that the $\eta\Lambda$-channel opening effect makes a peculiar peak-like structure at $M_{K^-p}\approx 1670$ MeV and nontrivial interference effects on the Dalitz plot for the charged channel.
