Identify hadron anomalous couplings at colliders
Abstract We investigate the identification of the Wess-Zumino-Witten (WZW) Lagrangian at colliders such as BESIII and the Super-τ-Charm Facility. Our analysis concentrates on the radiative decays of η and η ′ mesons, including η (′) → γγ, η (′) → γℓ + ℓ − , η (′) → π + π − γ, and η (′) → π + π − ℓ +...
