Heavy and strange holographic baryons

We extend the D4-D8 holographic construction to include three chiral and one heavy flavors, to describe heavy-light baryons with strangeness and their exotics. At strong coupling, the heavy meson always binds to the bulk instanton in the form of a flavor zero mode in the fundamental representation. We quantize the ensuing bound states using the collective quantization method, to obtain the spectra of heavy and strange baryons with both an explicit and hidden charm and bottom. Our results confirm the existence of two low-lying charmed pentaquark states with 1/2^-,3/2^- assignments and predict many new ones with both a charm and bottom. They also suggest a quartet of low-lying neutral Ωc⁰ with assignments 1/2^±,3/2^± that are heavier than the quintuplet of neutral Ωc⁰ recently reported by LHCb.
