Contribution
It introduces a chiral effective field theory approach that suppresses loop contributions outside the power-counting regime for studying baryon magnetic moments.
Findings
Identification of significant chiral curvature in QCD calculations
Insights into strange- and light-quark contributions to Lambda baryon magnetic moments
Potential for studying nontrivial quark behavior in baryons
Abstract
The utility of chiral effective field theory, constructed in a manner in which loop contributions are suppressed as one moves outside the power-counting regime, is explored for baryon magnetic moments. Opportunities for the study of significant chiral curvature in valence and full QCD and the nontrivial behavior of strange- and light-quark contributions to the magnetic moment of the Lambda baryon are highlighted.
