We investigate the hidden-charm pentaquarks as hadronic molecules of $Lambda_cbar{D}^{(ast)}$ and $Sigma_c^{(ast)}bar{D}^{(ast)}$ coupled to a compact core by employing an interaction satisfying the heavy quark and chiral symmetries. Our model can consistently explain the masses and decay widths of , and with spin parity assignments , and , respectively. We find that the mass ordering is dominantly determined by the short-range interaction given by coupling to the compact core, while the decay widths by the tensor force of the one-pion exchange.

Pentaquarks with or heavy quarks are very much interesting. We analyze the strange pentaquark with or in the coupled-channel quark cluster model. We find bound, resonance and cusp like states.
