TL;DR
This paper examines the role of $Z_3$ symmetry in QCD, revealing that in full QCD with dynamical fermions, the expected degeneracy of phases appears in observables without open triality, challenging previous assumptions.
Contribution
It provides a new perspective on $Z_3$ symmetry in QCD, showing that degeneracy manifests without open triality in the presence of dynamical fermions.
Findings
Full QCD with vanishing baryonic number lacks metastable phases.
Degeneracy of $Z_3$ phases appears in observables without open triality.
Challenges previous notions of phase degeneracy in QCD.
Abstract
Investigating the symmetry in Quantum Chromodynamics (QCD) we show that full QCD with a vacuum of vanishing baryonic number does not lead to metastable phases. Rather in QCD with dynamical fermions, the degeneracy of phases manifests itself in observables without open triality.
