# Baryon susceptibilities from a holographic equation of state

## TL;DR

This paper employs a holographic black hole model to study baryon susceptibilities in quark-gluon plasma, matching lattice data and exploring critical behavior at high densities, with implications for experimental detection of the critical end point.

## Contribution

It introduces a holographic model that reproduces lattice data and analyzes high order baryon susceptibilities to identify freeze-out conditions and potential experimental signatures of the critical end point.

## Key findings

- Reproduces lattice data at zero chemical potential
- Displays critical behavior at high densities
- Suggests experimental signatures for the critical end point

## Abstract

A black hole holographic model is used to mimic the behavior of the quark gluon plasma at finite temperature and density. This model reproduces lattice data at $\mu_B\!=\!0$ and displays critical behavior at large densities. High order baryon susceptibilities are used to extract freeze-out points by comparing those susceptibilities with the corresponding net-protons distribution measured by STAR. Possible experimental signatures of the critical end point are discussed.
