Topological quantization of vector meson anomalous couplings
Chao-Qiang Geng, Chia-Wei Liu, Yue-Liang Wu
We identify an overlooked Wess--Zumino--Witten structure in the hidden-local-symmetry~(HLS) formulation of vector mesons. The newly identified term generically leads to the topolog…

Identify hadron anomalous couplings at colliders
Chao-Qiang Geng, Chia-Wei Liu, Yue-Liang Wu
We investigate the identification of the Wess-Zumino-Witten (WZW) Lagrangian at colliders such as BESIII and the Super--Charm Facility. Our analysis concentrates on the radiativ…
