# Heavy and Strange Holographic Baryons

## TL;DR

This paper extends holographic models to include heavy and strange baryons, predicting new exotic states and confirming some observed particles using a strong coupling approach.

## Contribution

It introduces a holographic framework for heavy-light baryons with strangeness, providing predictions for new exotic states and spectra.

## Key findings

- Confirmed existence of two low-lying charmed penta-quark states
- Predicted many new states with charm and bottom
- Suggested a quartet of neutral $\\Omega_c^0$ states heavier than observed ones

## Abstract

We extend the $D4$-$D8$ holographic construction to include three chiral and one heavy flavor, 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 explicit and hidden charm and bottom. Our results confirm the existence of two low-lying charmed penta-quark states with $\frac 12^-,\frac 32^-$ assignments, and predict many new ones with both charm and bottom. They also suggest a quartet of low-lying neutral $\Omega_c^0$ with assignments $\frac 12^\pm ,\frac 32^\pm$ that are heavier than the quintuplet of neutral $\Omega_c^0$ recently reported by LHCb.
