The anomalous chiral Lagrangian of order
The European Physical Journal C-Particles and Fields, 2002•Springer
We construct the effective chiral Lagrangian for chiral perturbation theory in the mesonic odd-
intrinsic-parity sector at order p^6. The Lagrangian contains 24 in principle measurable
terms and no contact terms for the general case of N_f light flavors, 23 terms for three and 5
for two flavors. In the two flavor case we need a total of 13 terms if an external singlet vector
field is included. We discuss and implement the methods used to reduce to a minimal set.
The infinite parts needed for renormalization are calculated and presented as well.

Abstract
We construct the effective chiral Lagrangian for chiral perturbation theory in the mesonic odd-intrinsic-parity sector at order . The Lagrangian contains 24 in principle measurable terms and no contact terms for the general case of light flavors, 23 terms for three and 5 for two flavors. In the two flavor case we need a total of 13 terms if an external singlet vector field is included. We discuss and implement the methods used to reduce to a minimal set. The infinite parts needed for renormalization are calculated and presented as well.
