In the framework of quark delocalization color screening model, the three new reported pentaquarks Pc(4312), Pc(4440), and Pc(4457) can be identified as the hidden-charm molecular states ΣcD with JP=21−, ΣcD∗ with JP=23−, and ΣcD∗ with JP=21−, in the baryon-meson scattering process, respectively. Besides, the Σc∗D∗ of both JP=21− and JP=23− are also possible molecular pentaquarks. Moreover, the calculation is extended to the Pc−like molecular pentaquarks Pb. Several states with masses above 11 GeV and narrow width are obtained. All these heavy pentaquarks are worth searching in the future experiments.
