Baryon Mass and Phase Transitions in Large N Gauge Theory

TL;DR

This paper uses AdS/CFT correspondence to calculate baryon mass in large N gauge theory, revealing it as a bound state and identifying a phase transition at a critical temperature, along with bound states in the Higgs phase.

Contribution

It provides a novel calculation of baryon mass in large N gauge theory and uncovers phase transition behavior and bound states in different phases.

Findings

Baryon is a truly bound state in certain conditions.

A phase transition occurs at a critical temperature.

Bound states of W-bosons exist in the Higgs phase.

Abstract

We calculate the baryon mass in N=4 large $N$ gauge theory by means of AdS/CFT correspondence and show that it is a truly bound state, at least in some situations. We find that a phase transition occurs at a critical temperature. Furthermore, we find there are bound states of W-bosons in the Higgs phase, where the gauge group is broken to SU(N_1)xSU(N_2).
