Abstract
We study N and hidden-charm baryon resonances that are generated dynamically from the s-wave interaction of pseudoscalar and vector mesons with and baryons. We use a unitary coupled-channels model that fulfills heavy-quark spin symmetry and respects spin-flavor symmetry in the light sector. We predict seven N-like and five -like states with masses around 4 GeV, most of them as bound states. Some of these states form heavy-quark spin multiplets, which are almost degenerate in mass.
