Description
Recently, a novel pentaquark picture ($Qqq\bar{q}q$) in addition to the conventional three-quark one ($Qqq$) for describing the Roper-like singly heavy baryons such as $\Lambda_c(2765)$ and $\Xi_c(2970)$ has been invented, based on a chiral model. In this talk, I review roles of chiral symmetry and the $U(1)_A$ axial anomaly for those two states, and present our prediction of the existence of a negative-parity and 5-quark dominant $\Lambda_c$ baryon.
