TL;DR
This paper investigates the phase structure of zero temperature twisted mass lattice QCD, revealing strong metastabilities in the plaquette observable near zero untwisted quark mass, which impacts understanding of lattice QCD behavior.
Contribution
It provides new insights into the phase structure and metastability phenomena in twisted mass lattice QCD at zero temperature.
Findings
Strong metastabilities observed in the plaquette observable.
Metastabilities occur when the untwisted quark mass crosses zero.
Results inform the understanding of phase transitions in lattice QCD.
Abstract
The phase structure of zero temperature twisted mass lattice QCD is investigated. We find strong metastabilities in the plaquette observable when the untwisted quark mass sweeps across zero.
