High spin baryon in hot strongly coupled plasma

TL;DR

This paper models high spin baryons in a hot, strongly coupled plasma using holography, revealing how their screening length decreases with increasing spin, indicating easier dissociation at high angular velocities.

Contribution

It introduces a holographic model for high spin baryons at finite temperature, analyzing the spin dependence of their screening length and dissociation behavior.

Findings

High spin baryons dissociate more easily at high angular velocity.

The screening length decreases with increasing spin, indicating easier dissociation.

The model relates angular momentum and energy squared for baryons.

Abstract

We consider a strings-junction holographic model of probe baryon in the finite-temperature supersymmetric Yang-Mills dual of the AdS-Schwarzschild black hole background. In particular, we investigate the screening length for high spin baryon composed of rotating N_c heavy quarks. To rotate quarks by finite force, we put hard infrared cutoff in the bulk and give quarks finite mass. We find that N_c microscopic strings are embedded reasonably in the bulk geometry when they have finite angular velocity \omega, similar to the meson case. By defining the screening length as the critical separation of quarks, we compute the \omega dependence of the baryon screening length numerically and obtain a reasonable result which shows that baryons with high spin dissociate more easily. Finally, we discuss the relation between J and E^2 for baryons.
