Physical Nucleon Properties from Lattice QCD

TL;DR

This paper uses highly precise lattice QCD data and advanced chiral extrapolation methods to accurately determine the physical nucleon mass with less than one percent systematic error.

Contribution

It introduces a refined approach combining accurate lattice data with modern extrapolation techniques to improve nucleon mass predictions.

Findings

Nucleon mass estimated with less than 1% systematic error

Validated the effectiveness of modern chiral extrapolation methods

Provided a benchmark for future lattice QCD calculations

Abstract

We demonstrate that the extremely accurate lattice QCD data for the mass of the nucleon recently obtained by CP-PACS, combined with modern chiral extrapolation techniques, leads to a value for the mass of the physical nucleon which has a systematic error of less than one percent.
