Fundamental Matter and the Deconfining Phase Transition in 2+1 D

TL;DR

This paper investigates how heavy fundamental matter influences the deconfining phase transition in a 2+1 dimensional gauge theory, revealing a crossover behavior and mapping the critical theory to a 2D Ising model in a magnetic field.

Contribution

It demonstrates that fundamental matter turns the phase transition into a crossover and provides a mapping to the 2D Ising model to analyze this behavior.

Findings

Transition becomes a crossover with fundamental matter

Width of crossover region depends on fundamental mass

Specific heat varies with fundamental mass

Abstract

We analyze the effect of heavy fundamentally charged particles on the finite temperature deconfining phase transition in the 2+1 dimensional Georgi-Glashow model. We show that in the presence of fundamental matter the transition turns into a crossover. The near critical theory is mapped onto the 2 dimensional Ising model in an external magnetic field. Using this mapping we determine the width of the crossover region as well as the specific heat as a function of the fundamental mass.
