The anomalous Lagrangian in ChPT at NNLO
Johan Bijnens, Nils Hermansson-Truedsson, Joan Ruiz-Vidal
The anomalous Lagrangian in mesonic Chiral Perturbation Theory, of odd intrinsic parity, is determined to next-to-next-to-leading order thereby completing the order Lagrangia…

The anomalous chiral Lagrangian at order
Johan Bijnens, Nils Hermansson-Truedsson, Joan Ruiz-Vidal
We derive the order Lagrangian of odd intrinsic parity for mesonic chiral perturbation theory, and provide the resulting operator basis in the supplementary material. Neglect…
