Exact Chiral Symmetry on the Lattice

TL;DR

Recent advances have shown that chiral symmetry can be exactly preserved on the lattice, challenging longstanding beliefs and potentially transforming numerical quantum chromodynamics (QCD) research.

Contribution

This paper reviews developments demonstrating exact chiral symmetry on the lattice, providing a foundation for future research in lattice QCD.

Findings

Chiral symmetry can be preserved exactly on the lattice.

The mechanism is general and may be applicable in nature.

This breakthrough could revolutionize numerical QCD.

Abstract

Developments during the last eight years have refuted the folklore that chiral symmetries cannot be preserved on the lattice. The mechanism that permits chiral symmetry to coexist with the lattice is quite general and may work in Nature as well. The reconciliation between chiral symmetry and the lattice is likely to revolutionize the field of numerical QCD.
