A New Approach to the Problem of Dynamical Quarks in Numerical Simulations of Lattice QCD

TL;DR

This paper introduces a novel method for simulating dynamical quarks in lattice QCD by reformulating the problem as a local bosonic field theory, potentially enabling standard simulation algorithms.

Contribution

It presents a new theoretical approach to incorporate dynamical quarks in lattice QCD simulations using a local bosonic field formulation.

Findings

The bosonic formulation has a real, bounded action facilitating simulations.

The approach is theoretically feasible but lacks practical implementation tests.

Potential for applying standard algorithms to dynamical quark simulations.

Abstract

Lattice QCD with an even number of degenerate quark flavours is shown to be a limit of a local bosonic field theory. The action of the bosonic theory is real and bounded from below so that standard simulation algorithms can be expected to apply. The feasibility of such calculations is discussed, but no practical tests have yet been made.
