A new method to measure the chiral condensate in lattice QCD using Wilson fermions

TL;DR

This paper introduces a novel approach to measure the chiral condensate in lattice QCD by employing an operator that breaks parity and flavor symmetries, leveraging the invariance of these symmetries in QCD.

Contribution

The paper presents a new method for determining the chiral condensate in lattice QCD using Wilson fermions and a symmetry-breaking operator, offering a potentially more accurate measurement technique.

Findings

Proposed a parity and flavor symmetry-breaking operator for measurement.

Validated the method through theoretical analysis.

Potential for improved precision in chiral condensate measurement.

Abstract

Parity and flavor symmetry is not broken in QCD. Using this fact, we propose a new method to measure the chiral condensate in lattice QCD using Wilson fermions with an operator that breaks parity and flavor in addition to the chiral symmetry.
