N and $\mathrm{\Delta }$ hidden-charm resonances with heavy-quark spin symmetry

We study N and $\mathrm{\Delta }$ hidden-charm baryon resonances that are generated dynamically from the s-wave interaction of pseudoscalar and vector mesons with $1\mathrm{/}{2}^{+}$ and $3\mathrm{/}{2}^{+}$ 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 $\mathrm{\Delta }$-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.
