Jack Laiho
TL;DR
This paper discusses the use of next-to-leading order (NLO) (partially quenched) chiral perturbation theory to extract the ratio / from lattice QCD data, improving theoretical understanding.
Contribution
It introduces a method for applying NLO (PQ)ChPT to lattice data for / extraction, which is a novel approach.
Findings
NLO (PQ)ChPT provides a framework for / analysis.
Results facilitate more accurate lattice determinations of /.
Discussion of theoretical uncertainties in the extraction process.
Abstract
Results at NLO in (PQ)ChPT for extracting from lattice data are discussed.
