Color confinement and dual superconductivity of the vacuum. IV

TL;DR

This paper analyzes monopole condensation in N_f=2 QCD near the deconfining transition, finding evidence for a first order transition and reviewing the role of dual superconductivity in color confinement.

Contribution

It provides a scaling analysis of the monopole condensation order parameter and discusses the nature of the deconfining transition in N_f=2 QCD.

Findings

Scaling analysis supports a first order deconfining transition.

Dual superconductivity remains a viable mechanism for color confinement.

The study aligns with previous specific heat scaling results.

Abstract

A scaling analysis is made of the order parameter describing monopole condensation at the deconfining transition of N_f=2 QCD around the chiral point. In accordance with scaling properties of the specific heat, studied in a previous paper, scaling is consistent with a first order transition. The status of dual superconductivity of the vacuum as a mechanism of color confinement is reviewed.
