One-loop unifying relations between Yang-Mills theory and the nonlinear sigma model from Berends-Giele currents
Year: 2026
Type: preprint
Abstract: We study unifying relations between Yang-Mills theory and the nonlinear sigma model. We extend tree-level amplitude relations expressed through differential operators to off-shell multiparticle currents and obtain one-loop integrand relations by sewing two off-shell legs. This off-shell approach may also apply to higher-loop integrands.
