Kavli Affiliate: Jia Liu | First 5 Authors: Yang Bai, Ting-Kuo Chen, Jia Liu, Xiaolin Ma, | Summary: We present a complete Lagrangian describing axion interactions with pseudoscalar and (axial-)vector mesons within the three light-flavor quark framework. This formulation incorporates both the standard chiral Lagrangian and the full Wess-Zumino-Witten (WZW) term. By including instanton effects […]
