Dual Superconductivity and Chiral Symmetry in Full QCD

TL;DR

This paper investigates the relationship between dual superconductivity and chiral symmetry in full QCD, showing that the disorder parameter behaves similarly across the phase transition as in the quenched case.

Contribution

It provides the first measurement of the disorder parameter in full QCD with dynamical fermions across the chiral transition, extending previous quenched studies.

Findings

Disorder parameter indicates dual superconductivity persists across the transition.

Behavior of the disorder parameter in full QCD is similar to the quenched approximation.

Results support the dual superconductor model of confinement.

Abstract

A disorder parameter detecting dual superconductivity of the vacuum is measured across the chiral phase transition in full QCD with two flavours of dynamical staggered fermions. The observed behaviour is similar to the quenched case.
